Firefox Support Forum

Hi,

I was using FF on Ubuntu 22.04.4 LTS. Had version FF 120.x and playing video in Netflix worked fine. Then I updated to FF 124.x and playing video stopped with error F7355-1203.

I've checked the DRM setting and it is enabled, I checked addons and I have OpenH264 and Widevine installed, both set to always active.

I've checked installed codecs and I do have libavcodec58 installed. No update for that available via apt. I also have ffmpeg installed, no problem with that either. I can play Netflix videos in Chrome, but not in Firefox now. Something happened to Firefox when I updated from 120.x to 124.x. Today I updated to 125.x, same problem, Netflix video won't play.

I've unchecked the DRM setting and re-checked it, and that does reinstalled Widevine but does not fix the problem.

Any ideas what could be the cause?

Greetings, I am Alvimutmex. A "not supported" notice shows up each time the Mozilla browser loads a webpage. After looking through the settings, I discovered that Mozilla has to be updated. Could you please help me update Mozilla? For instance, when I attempt to open (https://phoneinsurance.us/), I get an error warning.

When you added a bookmark to a site in Firefox there used to be an option that when you hovered over the bookmark a dropdown would appear showing recent changes or additions to the site (see attached). It doesn't seem to be there any more - is there any means of restoring it? Thank you.

I keep getting this message that pops up in a private window to restart to keep using firefox. Everytime I click restart Firefox, it closes my tabs and opens them again. However, 5 minutes later the window pops up again. Even after repeated attempts of updating, even doing a full restart on the computer, Firefox continues to send this window to me. The private window in the bar says about:restartrequired.

I've tried uninstalling Firefox with a fresh install as well as doing a Refresh of Firefox. Neither seem to solve this problem.

Please see the attached screenshot. I get this popup EVERY TIME I open FireFox. I've tried a number of different suggested "fixes" from Google Searches with no success.

I want this popup GONE.

Concurrent with the most recent automatic windows update (may or may not be the problem), Firefox with duck-duck-go will not go to almost any site. All I get is a spinning icon or a blank page, not even any error messages. This was even true trying to go to this page until I restarted in trouble shooting mode. Until I can get Firefox working again I have been using Chrome with duck-duck-go. Note any search, i.e. 'hotels in Italy' or even 'MSN' do the same: spinning icon or blank page!! Any help would be appreciated. Also I noticed that my bookmarks were missing and there was no bookmarks drop-down on my tools line. I have run malware bytes and it showed clean, same with CCleaner. I have re-installed Firefox; no difference. Please help. and also, any way to find and replace my extensive bookmarks list? I have reduced my privacy to near zero and turned off firewalls and all limits I could find while testing for that. That did not change anything.

When I click on the link for Hyperallergic Magazine, the page doesn't load. I don't have it blocked in Notifications. I have allowed pop-up windows for it. I can't figure out what else might be preventing it from loading. It is free. I don't have this problem with any other website that I know of. I'm running the latest version of Firefox & have Windows 11 on a one-year-old PC. I didn't have this problem in my old computer, which ran Windows 7. Please help. Thanks.

Greetings everyone,

I've had this problem for a while and I don't know what to do.

I had a problem where Firefox kept crashing before it had finished loading up all of my former tabs and windows and so I was given the option of opening Firefox in "Safe mode" which I did, but now Firefox only starts in "Safe mode"...

I'm running the most up to date version of Firefox.

Thank you for any help!

https://register.ridgidpower.com/# is not working. Specifically the Sign-In link. It works just fine with MS Edge. I had all extensions off, anti-virus off and I also cleared the cache twice, and also followed the Help/Troubleshoot Mode to no avail. I'm using V125.0.1 64bit

When I run firefox on WSL2, buttons dont work on any pop up windows. Foe example when installing a firefox extention - it will download and pop up a small window at the top right to add the extentionto firefox. The buttons dont work. Another example is when opening up the firefox menu bar (hamburger bar) - it will pup up a small window to allow to open up settings, go to add ons, open bookmarks or history. The buttons dont work. Last example is the pop up window for this Ash your question page for firefox support - When clicking "Which topic best described your question - it will pop up a small window to select what type of question Im gonna ask. The buttons dont work.

I dont know how to fix this. I restarted, deleted my firefox profile, started of safe mode, nothing worked. How do I solve this issue?

Even after numerous Uninstalls and a Reinstalls I keep getting this error notice when trying to open Firefox...

The application was unable to start correctly (0xc0000022)
