Firefox Support Forum

Firefox update (about 4 weeks ago?) resulted in losing access to various accounts eg: bank, health care provider. Forced to use Chrome (blech!) Websites now state that I'm using an "unsupported browser". Have contacted host sites and they are unresponsive and/or unable to provide solution. Can still access bank etc from Android phone but forced to use other browsers from MacBook Pro.

Thank you for your assistance!

Figured out the basic issue (from Solutions here) why old Firefox not working on old XP-SP3. Found 52.9.0esr download - but when I run the file, it keeps telling me to "Close Firefox". Used Task Manager - nothing - not Firefox or anything else - is shown to be running. Any ideas? Might not be a Firefox issue, but would appreciate any insights. TIA - Jean

I couldn't get the crash data at all. But I managed to get this from the Terminal;

[Child 10502, MediaDecoderStateMachine #4] WARNING: Decoder=7f0fd7cf1400 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) - RefPtr<mozilla::MozPromise<RefPtr<mozilla::MediaTrackDemuxer::SamplesHolder>, mozilla::MediaResult, true> > mozilla::MediaSourceTrackDemuxer::DoGetSamples(int32_t): manager is detached.: file ./dom/media/MediaDecoderStateMachine.cpp, line 3470 Exiting due to channel error.

Firefox ESR 52.9.0 (32-bit) Facebook Comment Issue: When typing a comment in Facebook letters type right to left instead of typing left to right. This causes the comment to be typed backwards Example "Birthday" would be yadhtriB.

When I try to use a platform like Netflix i get repeated error messages that WidevineCdm has crashed. This happens also in other browsers. I am not very tech savvy, but I've tried all the solutions I was able to understand on here and through Google, but nothing seems to fix the problem. Can any one advise?

Not sure if this helps, but here is one of the many crash reports I've sent: https://crash-stats.mozilla.org/report/index/75e61622-4282-4a83-b86e-9861a0210422

I've written about this before, but no help? I'm using Firefox Mac 78.15 (up to date). When I go to CNN and select a video, a thumbnail (still image) of the video appears, but no player with controls, so no video. When I do the same on Chrome, I get a video in a video player, which plays just fine. Also, all other videos on FIrefox (YouTube Fox News, etc.) play just fine?

I was using one of the old Firefox ESR versions (can't remember exactly which) because I was still on an old Mac OS version, 10.9 to be more specific.

I recently updated to macOS Sierra 10.12.6 and as a result, as soon as I opened Firefox, I went to check if it would update on its own and it did. It updated to version 91.6.0 esr. After this update, something weird happened: the browser won't load any page.

I checked, it's not an internet connection, because other browsers are working normally. It won't load any extensions either. So I want to fix this issue with an update.

The question is this: I remember installing what was called Firefox Quantum. As of now, the name on the about section is just Firefox Browser, maybe because of the updates. • Can I install the latest "regular" Firefox 97.0 on top of the this old installation, just using a standalone dmg file? • Will this installation preserve everything that's already in the browser? By everything I mean bookmarks, extensions, history, cookies, etc.

It seems to me that the automatic updater isn't installing version 97.0 on its own because it's coming from the ESR versions. So it's stopped at 91.6.0 esr.

Thanks in advance

Hello,

It is suspected that latest version of Firefox version 78.11.0esr (64-bit) is causing operathing systems to crash. I have not seen it on Windows platform as I am not using it. Platforms I am using are OSX and XUbuntu. The error occurs lingering on a site for a very long time. First it starts getting screen graphic errors like, some pixels are not being updated correctly. Then after a while screen starts to flicker, in a massive state, like the graphic processor is broken. In some cases with command key strokes one is able to kill Firefox, screen is back to normal and one can continue working. Facebook is the site that most commonly is causing error, but there are also other sites.

Hello, I have issues with some (not all) websites. The problem is that text is not displaying properly all of a sudden. Some letters display and the rest not. The text can be highlighted but still not displaying. I tried to refresh Firefox, Restart with Add-ONs disabled, tried to reinstall FIrefox. Manually tried to disable all Add-ons as well. Then I tried some of the suggestions here https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Set-Cookie/SameSite#browser_compatibility

No matter what I try it's not working well. There was a browser update to version 78.12.0esr (64-bit) made around 20 days ago and had no issues till now. I'm used to Firefox and using it for work a lot and prefer to keep using it. Buttons (links) are not displaying as well but are clickable and opening the content. Screenshots are uploaded as well.

If anyone could suggest how to work it out would be much appreciated. If other details are needed please let me know.

Thank you!

am seeing an issue in firefox on unix with accessing a web page which uses basic http authentication mechanism. It pops up for user id and password for basic authentication. When I enter the credentials and click submit the response received is 401 Unauthorized. Same webpage and authentication works in chrome browser on same system (so assuming no firewall issues). The Firefox and chrome is configured in a console where we test it. And both are requesting for the same host. I believe there is some configurations issue in Mozilla firefox that might be affecting it. Attaching the request and response for both.

Trying to play video included in Amazon Prime subscription. I received a warning from Amazon about 2 weeks ago that After Dec 6 I would need the latest Firefox update. I updated. Now as shortly after video starts to lord, I get a message in a box that says I need to upgrade Firefox to play this video. I have checked the "about Firefox" tab and it says I am up to date. I am running 91.4.0esr and checkbox says I am up to date. ????

Hi, volunteers!

About an every every hour or two, Firefox shows a compelled "Restart required" page with a "Firefox has just been updated in the background" message, which yet absolutely sure has nothing to do with disabled automatic updates.

These and pyllyukko's user.js preferences have been set:

• browser.cache.disk.enable;false
• browser.cache.disk_cache_ssl;false
• browser.cache.memory.capacity;5000000 # -1
• browser.cache.memory.enable;true

The page is shown either hard or solid state drive is used with 8 GB RAM on board, `free -h` shows more than enough. "Storage disk location" value for `memory` and `disk` (except `appcache`) from the `about:cache` page is "none, only stored in memory".

Appreciate your time and efforts, this message haunts me no matter what for so long.

I am no longer able to connect to my tangerine bank account with Firefox. I have no problem with Safari. I cleared the cache and deleted the cookies, to no avail. i have iMac with Macos 10.15.7 and Firefox 70.22 78.12.0

Firefox will not load dropbox except the top left corner sometimes, even with ghostery paused. There's no problem on Microsoft Edge at all. Anyone else experiencing this?

Hi there,

Firefox is my daily browser and a few websites are causing recurrent issues. Aliexpress randomly switches language and currency, but the most annoying problem is that it doesn't let me change it (clicking on it doesn't give the menu it's supposed to give), and searching any item in the search bar just gives the "spinning star symbol", and nothing else.

Similar issue in eBay: some menus just don't open, including submenus in the "Contact seller" form, which cripples the whole experience.

As a comparison: all these websites work fine in a slightly outdated Safari 14.1.2. and the most recent Vivaldi.

Now, I saw the issue being mentioned here 4 years ago.

What I tried:

1. cookie /cache cleaning, which I did to no avail.
2. Safe mode: no change
3. Switched back privacy settings to "Standard": no change.
4. Manually copied files from one profile folder to another: as could be expected, no change.
5. I even tried a full refresh, but with extensive customization already performed over the years and most of it either in about:config or extensions, I couldn't spend the time re-setting everything back to normal.

FWIW a list of all files and folders shown in my profile folder. I specifically excluded the "known good" files (see step 4). Interestingly, FF also generated an "Invalidprefs.js" file.

Has Mozilla stopped processing crash reports for older versions of Firefox like Firefox ESR v52.9.0 (the legacy version for Win XP and Vista)? I tried to filter crash reports on the Mozilla Crash Report site at https://crash-stats.mozilla.org/home/product/Firefox for older versions of Firefox but I can't select a Firefox version older than v68.4.1 (i.e., the current FF ESR version) - see attached image.

I'm trying to assist a Vista SP2 / Firefox ESR v52.9.0 user who is trying to troubleshoot their browser crashes but they've told me they are having problems submitting their crash reports from about:crashes. I just want to make sure that Mozilla is still processing crash reports for older version of Firefox if the user submits them from about:crashes manually, assuming the crash report is less than 6 months old.

Hi There,

we have an issue here, sometimes when we try to open a page on the new tab it will not working.

This only happens after we update our firefox to version91.3.0esr(64 bit).

Could you please have a look ?

Thank you

I am using version 91.5.0esr (64-bit). Virtually always, the download status shows as failed. Yet, there were files created by the download. I have even been able to go back literally months in the downloads history, click to retry each download, which is then showed as being successful. I did NOT reload the pages whose content I was trying to download. I realize that a browser tends to have a cache, but surely not that big. I'm guessing that showing the status failed is some type of error.
