Mozilla comes up but cannot go to any site, my other browsers work just fine

I shut down at night, when I started up again the next morning, the browser came on, but it did not load my favorites and did not allow me to engage anything on the web. It has not worked since the morning of 2/12/20.
My other browsers work just fine, only yours does not work, why is this?
This makes things difficult as I have several things that run off this account that I cannot now access, or at least without difficulty. Did your whole site go down? When can I expect it to be back up?
I do enjoy using your browser, and it has never failed me before, I do hope you can get it up and running very soon.

Mozilla Firefox 70.xxxx

Started about 11/20/2019 give or take a day or two.

Ever since Win 10 made its latest update to 1903 ( I delayed it on win 10 pro), Firefox is SLOOOOOOOOOOW. So slow its almost unusable.

Actually, I'm not sure if its a win 10 update or an update to Firefox 70.0.1.0.

I have over 600 tabs so I have been deleting tabs to no effect.

I also stopped all extensions and went into safe mode - to no effect.

Mozilla firefox

I have been using Firefox on two generations each of a desktop and a laptop with great satisfaction and convinced my three daughters to use it as well.

However, when I tried to start up on my desktop yesterday I was greeted with the message COULDN'T LOAD XPCOM. I retried a number of times, and discovered that when I clicked on a link in various emails I received I got the same message.

My laptop is strill working as usual with Firefox.

If I cannot upload XPCOM should I uninstall Firefix and re-download it? I fear that by doing that I will lose all my bookmarks. Is that so?

I'd be grateful for advice soon.

Many thanks

Peter Tallentire

Mozilla papgamez.com

I looked at this site as it claimed to deliver all favorite movies & games for free on minimum fees. I started filling out some of my bank details but then just had a feeling that it wasn't a legitimate site so didn't consent or submit anything just got out of that internet page.
Just this morning I checked my bank app & Papgamez has debited $72 out of my account. I went to the bank immediately. They couldn't help & said if I filled even the slightest details that the onus of fault was mine! And to try to call or email. What part of fraudulent scam did they not understand? There is no email or phone number I can call. Even if there was it will only alert the scanners I am on to them. They would wipe my bank account clean. I have taken all my money out of the account. I will also closing the whole account down.
Just so frustrating as the culprits won't be held accountable. And it's the money loss plus the inconvenience of changing all the details linked to that bank account. As in other household bills that are debited from that account.
YES - Papgamez is 100% A SCAM

Mozilla firefox browser

When posting news articles to social media, I have an open tab for minds. com. Almost every day, when I have copied the web address of an article, and click on the media tab to post, suddenly the page jumps, and I now have two pages open. One with a single tab, which I just clicked on, and the original page with multiple tabs. This started with 66.

Mozilla add on services of mozilla

This complaint is for Mozilla Firefox's Addon: The User Switcher.

There is a fake one that duplicates the authentic User Switcher: https://addons.mozilla.org/en-US/firefox/addon/user-agent-switcher-revived/.

The REAL one is this: https://addons.mozilla.org/en-US/firefox/addon/uaswitcher/

The fake one uses a different icon, and the platform uses icons instead of the text lists that are found in the authentic User Switcher.

Please look into this.

Mozilla firefox app ver. 17.3 (15323)

You cannot clear out the Web Data that lists every Web site that you went to separately. Make that possible again and fix your Java. Please, hire some better people. You tap the red minus area and the entry will not delete. You have to fix that because even trying to force mobile browsing app tracking should be not allowed. That's crazy. That is the only way to get rid of cookies using that app on your phone. Just take care of it.

The Website Data is located within Data Management. You have to select Clear All instead of any one listing. You cannot treat phone customers that way about where people touch their glass screens. Thanks

Mozilla firefox

Why does firefox use trackers on there clients? they profess to be a neutral non tracking non data mining company yet using their program tracks your usage and location worse than or as bad as any other internet browser. They are liars they use some of the nastiest most dangerous trackers available to track their clients on the net. I have tested firefox trackers with 6 different spy/ malware programs and everyone has found nasty trackers used by firefox/ mozilla. They use a geo tracker which comes up as extremely dangerous by all 6 spy/ malware programs I have used.
Please be aware this company lies to it clients.

Mozilla mozilla firefox

I was working on schoolwork that does not automatically save and your terrible service crashed out of nowhere. It did not save anything. I restarted on the far superior google chrome, where I had no problems whatsoever. I uninstalled your terrible application and now I will be using chrome permanently. I would say fix it, but hey, google is going to buy you out in a few years anyways so whats the point.

Mozilla a pocket recommendation

Hi there.

Just yesterday, while I was getting ready to look up something pertaining to my writing, I saw a certain disturbing "story", which was a Pocket Recommendation. It mentioned one male cousin who was brutalized by another. And since I found the article highly-disturbing, I find myself offended enough to complain to your company about it. I seriously did not need to see something so disturbing in the form of a so-called 'recommendation'. It doesn't matter how lengthy or 'wordy' it is as an "article". What matters is the content of such articles. If you're going to continue to be a reliable browser, then you need to show and/or tell people how to opt out of this content BEFORE they stumble upon something which may rattle their emotions.

Mozilla mozilla browsers

Mozilla is now bumping Dissenter extensions of of Firefox. Don't bother using Firefox, since their browser works badly, plus doesn't support free speech. Might as well use Chrome or Safari, since they work better, and since all browsers are now run by SJW sociopaths.

Would someone out there please develop a free-speech-oriented browser? I would really appreciate that.

Mozilla the installation of addons into the web browser

5th May 2019
Initially, all of my addons and web extensions were deemed unsafe and were removed from Firefox, even after using these addons for more than 8 months, then when I tried reinstalling those addons, the message "Download failed, check your connection" will pop up. I have tried it for numerous addons and themes, including the ones that were preciously downloaded, but nothing worked.
Fix this problem because it is annoying having to go on without the browser extensions that I have been using for a long time now, and I'm sure other people are having the same problem with their browser!
Please do something about this!

Mozilla dissenter ban : judas firefox attack free speech

First FF barred Dissenter from their platform forcing people to install it from elsewhere.
Next, after 15 tears of treating us as adults with "I understand the risks but wish to proceed" FF make it impossible to install unapproved addons
Worse they actively deceive by claiming that the Dissenter xpi is 'corrupted'.
Are we expected to believe this is all 'for security'? If so what happend to the last 15 years?
Happily, as ever, the internet provides a solution to censorship - Gab are creating their own dissenter-friendly browser based on Brave... itself made by ex FF staff.
Sweet.

Mozilla firefox

Suddenly, firefox has rejected all of my addons. I tried to replace my DuckDuckgo but it failed. But if you release an update sure some applications may no longer be compliant but it should not be ALL of them. Mozilla seems to be getting more klunky. After a previous update I could no longer apply beautiful themes just flat simple boring themes but that was acceptable, although not desirable. Furthermore, the select category list is completely inappropriate for the nature of the provider of the service to which this issue belongs. I doubt that this information would even come to the attention of those whom it concerns.
