Firefox 技術支援討論區

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?

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.

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.

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!

and i couldn't figure out how to do it. if anyone can tell me steps on how to do it i'll be glad.

thanks.

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)

I've received my new PC and will be migrating from my old PC (Windows 10) to the new PC with Windows 11.

I use local folders in Thunderbird to keep various projects separate and more easy to manage. I have copied the current Thunderbird profile on to an external hard disk, I have found the location of the local folders and they reflect the structure in the Thunderbird screen I see. Thunderbird has been unstable for a few weeks so I would prefer a clean install but don't want to lose a lot of content that I still need.

1. Is there a way to copy over just the local folders, eg export them, rather than the whole profile? I deliberately haven't cleaned the server recently so that I can get back emails that still are in the in_tray but once they are in local folders they disappear from the Yahoo server. 2. Is there anything else significant I should be aware of before migrating? There is a backup on Mozilla but I prefer a clean install.

Thanks in advance,

Anne

Whenever I have Firefox open on Windows 11, my windows key doesn't work. I can assure that its Firefox because whenever I close it, the windows key starts working again. This is really annoying because I normally use the keyboard and having to move my mouse to the bottom just to open the menu gets annoying quick.

I always want the address bar suggestions to start with my bookmarks. Is there a way to control the results? I remember there was something in about:config previously.
