Dear Support,

I am using Pulse SMS in Firefox 94.01 in Windows 10, https://pulsesms.app. I receive MP4 videos via this SMS web application and Firefox will not open them, they are coming from an Apple IPHONE. I receive the following error and the video will not play.

No Video with supported format and MIME type found

I open the same Pulse SMS app in Google Chrome, MS Edge, Vivaldi and each of those applications plays back the video fine and I hear the sound. I have disabled all extensions in Firefox, and also allowed all all the Site permissions for the web app site, I have turned off enhance tracking, note of the firefox settings seem to help The MP4 will not play. Can anyone point me to a setting that might allow me to playback these videos? I have looked thru the history of Firefox and it seems to be an issue that rears it's head quite often over the years. If anyone has a solution could you please let me know. thank you for your help!

Extension.json file seems to be corrupting each reboot

Hiya, I've been having trouble with my firefox since about a week ago:

The plugin Simple Tab Groups refuses to load & while all other extensions still function correctly besides Simple Tab Groups, I cannot access the extensions page when STG is broken as it also breaks. Not loading any extensions or themes. I've tried firefox with STG disabled & nothing breaks the way it is when STG is enabled. So it's some interaction there.

The only fix I've found is deleting the extensions.json file in my firefox profile folder, but that only works for one session. The moment I close & reopen firefox it appears broken again.

I've already emailed the developer but they havent replied & this seems it could be an issue with Firefox seeing as the extension works fine when extensions.json has been remade.

Here's my 'about:support' info-dump: https://pastebin.com/1FZFudmi

Any help would be appreciated !

Firefox still won't play the videos on MSN websites. All other websites are ok. This is a known problem that goes back almost ten years now.

All cookies and other cache items have been cleared and Firefox has been refreshed and it still does the same exact thing only on MSN websites. All other websites are ok and all other browsers except Firefox have no issues playing videos on MSN.

Firefox freezes when calling context menus and opening new windows

This has been a persistent problem for me. I first posted about it here. Since then problem has gotten progressively worse - the number of scenarios where the freeze happens has expanded and the frequency has increased. The gist of the problem is that Firefox freezes: a white transparent overlay appears over the window, the interface stops responding and no crash report is generated.

When it happens:

1) When calling any sort of context menus and dialogs. It first began to happen when interacting with autofill menus for input forms, but now it happens with any context menu - input forms, file save dialogs, menus in the menu tab and even the right click context menu.

2) When opening new windows (notably NOT new tabs) such as when opening a private browsing window, bookmarks window, download history window or when using the picture-in-picture option on Youtube.

How frequently it happens:

The frequency appears to be random and not specific to any website. It used to happen after about an hour of browsing, but after I attempted a clean reinstall of the browser (see below) the frequency increased dramatically and I am now lucky to get half an hour of browsing before it restarts.

What I've tried so far:

1) Looking for problematic extensions. Running Firefox in safe/troubleshooting mode seems to prevent the issue, so I started disabling extensions one by one. Ultimately though, even with all extensions disabled outside of safe mode, the issue persists. Reinstalling the browser without installing any extensions also does not resolve the issue, so any extension-related problems are seemingly ruled out.

2) Tracking memory and CPU usage. Nothing abnormal there - I have 16 GB of memory and Firefox rarely goes over 5. Just in case, I also increased the page file size on the main drive where Firefox is installed and enabled page files on all local drives (it was disabled for 3 out of 6 for some reason). This also didn't resolve the issue.

3) Refreshing Firefox. This did nothing except cause the 'Oops, there was a problem restoring your session' tab to first start appearing. Before the refresh that didn't used to happen at restart.

4) Disabling hardware acceleration. No effect.

5) Removing bookmarks. I had a very large number of bookmarks saved so I tried removing all of them. The issue persisted.

6) Deleting the places database. No effect.

7) Deleting the session restore files. This has been the most interesting option. Deleting the session restore files DID stop the freezing... until it came back again in a couple of days. Deleting the session files again after that did not make the issue go away again.

8) Doing a complete reinstall of the browser. I uninstalled Firefox from the Control Panel, then went into the AppData folder and manually removed any references to Firefox. After that I installed the latest version of the browser and refrained from syncing the new instance with my Firefox Account, or installing any extensions. Even with that, the issue persists.

9) Checked for hardware problems. Tests of RAM and the SSD on which Firefox is installed produced no errors. The issue also persisted through a GPU upgrade. Barring some arcane motherboard or CPU issue, I think hardware problems are ruled out - and it seems unlikely that a motherboard or CPU hardware issue would affect Firefox and only Firefox.

Please help, this is an extremely frustrating problem and

When I click the fullscreen button on a video, such as YouTube or Netflix, I find that upon exiting the fullscreen video and going back to normal screen, Firefox's window size is now maximized, when it was a smaller window before clicking the fullscreen button.

I am running Ubuntu 21.10 and I don't recall having the issue in previous versions.

When I forward some links, rather than taking the recipient to the specific YouTube page, the link takes them to the YouTube home page. Other sites I can still forward correctly. I have researched this issue and except for a virus that affected Firefox a few years back, I have found nothing. I have run spyware, malware, and virusware with no change.

Is this a YouTube issue? Another form of Big Tech censorship? Anyone else out there having issues like this?

I finally put FireFox in the garbage can in my iMac (Big Sur 11.5.1) and flushed it and then downloaded a new copy. No difference. I deleted all my cookies per the Firefox suggested repair page. Why would a specific site generate these forward issues? Just for giggles, I tried a forward in Safari (which I never otherwise use) and the links work correctly.

I have been a Firefox supporter from the very beginning and hate to swap browsers. Thank you to all the wonderful code writers and tech support volunteers out there who make this effort possible.

I removed the 32 bit version of firefox some time ago and installed the Firefox 64 bit version on my larger secondary drive. Firefox recently updated but the update cause the same version of firefox (version 94.0.1 build 20211103134640) into multiple hard-drives (C & D drives) and different folders. There are now multiple icons in my start menu and the task bar for firefox. They BOTH each fight for the default browser setting as if they were different browsers, and only one will open my previous windows and tabs at startup. I only want firefox to be installed on my secondary drive as my C drive has a much smaller capacity. How can I distinguish and remove one of these conflicting multiple copies of Firefox from my PC without loosing my saved tabs or all of my personal data? Why is firefox installing as 2 different apps, on 2 different hard drives, along the same profile path in two different profile folders as shown with "more troubleshooting information" from the help dropdown menu?

I recently changed jobs and my old work email address is now closed. I had originally created the account using my personal gmail account, but changed the primary email to my old work email. Now I cannot create a new Firefox Sync account using my personal gmail since it is tied to this defunct Sync account. I can log in with the email and password, but it won't let me change any settings with my account without a verification code. I called a friend at my old work and there is no way for them to temporarily reactivate my email account.

Is there any way that I can get this account deleted without the verification code? I don't care if the data is lost. I wanted to start over from scratch anyways. I can view my profile data through the support page, but when I click on the delete account option, it continues to ask for the verification code. If there is a way on the back end to completely delete it, I would appreciate it.

Hello, When I try and go to some websites like https://source.android.com/ or https://developer.android.com/ the text on that webpage breaks. This seems to only happen on firefox and not other browsers such as brave or chrome. I have tried giving firefox a "tune up" and turning off my extensions with no luck. I have found a solution that works temporarily which is pressing ctrl + f5 to refresh the page but that stops working after I close the tab. Another problem is that on some websites such as https://www.metrobyt-mobile.com/ the navbar at the top wont load on firefox but would on other browsers. Any help with this would be greatly appreciated.

Today I ran into an issue I never experienced before and which I somehow can't fix. Whenever I hit the CTRL button (e.g. for CTRL+F, CTRL+A, CTRL+C, etc.) the zoom is decreased by 10%. Same goes when I use the CTRL button to zoom with the mouse wheel.

I'm using Firefox 94.0.1 (64-bit) under Windows 10

I tried closing the browser and opening it again, restarting the computer and using Firefox in Troubleshoot Mode, but the problem persists. A search in the forum here and on google yielded no relevant results.

Anybody who's got some good advice for me? Thank you very much.

  • When I try to print a webpage using Firefox, the page enlarges 4x and therefore I only get 1/4 of the webpage on an 8.5 x 11 sheet. If I change my browser to Chrome or IE, it prints correctly. If I scroll to the bottom of the Firefox Print Dialog window and select "Print using system dialog" it also works correctly.
  • I have the zoom set to 100 and the Print Dialog paper size set to Letter, It is set to print to page width, I tried it with Scale 100 but it didn't help. I also went to about: config and checked that the paper size and scaling were set to 1.
  • The the picture of the Print Preview looks exactly like should be when printed, but when it is sent to the Lexmark S505 printer the size is too large.
Since I print 50-100 individual webpages a week, I cannot use Firefox if this can't be corrected.

Whenever I type "f" into the address bar in FireFox the following auto populates and suggests:

place:folder=BOOKMARKS_MENU&folder=UNFILED_BOOKMARKS&folder=TOOLBAR&queryType=1&sort=12&maxResults=10&excludeQueries=1/

There are no folders named "BOOKMARKS_MENU" "UNFILED_BOOKMARKS" or "TOOLBAR" that can be found on the computer. Bookmarks Toolbar and Bookmarks Menu exist under Application Menu>Bookmarks>Manage Bookmarks. No "Unfiled" exists in Manage Bookmarks, an "Other Bookmarks" does exist.

If I uncheck the option for FireFox to auto fill suggestions from bookmarks it stops. But, obviously, that is not a good solution.

No other letter generates this suggestion.

Typing "s" auto fills and suggests:

place:sort=8&maxResults=10/

Typing "t" auto fills and suggests:

place:type=6&sort=14&maxResults=10/

No other single letter auto fills and suggests a "place:" formatted suggestion. All others just suggest bookmarks or nothing.
