Firefox Support Forum

When I launch FF after rebooting an annoying ad pops up on the new page tab, the contents are:

'Get the inside scoop

See the add-ons our staff use to make browsing faster, safer, or just plain fun!'

It pops up just under the puzzle piece icon next to the address bar.

Is there a way to block it?

No longer able to copy or paste text on Firefox with Windows 10. Copy and Paste are greyed out in the right click menu after selecting text. Using CTRL-C, V or P does nothing at all. Still works fine in other browsers. What has Firefox broken again this time?

Suddenly almost everytime I load a YouTube video I have to watch 2 - 4 min of ads, sometimes two in a row before the video starts. I no longer have the skip ad button. If I load the same link in Chrome or Edge I don't have this problem. My search engine is Duck Duck Go, but if I go to Google first and then to the video I still have the problem. I also have the Maleware Bytes ad blocker installed. Any suggestions?

Hi all,

I feel like this is a problem that must have been experienced and solved a thousand times... however I've tried all the suggested fixes I can find and the problem still persists.

When I load Firefox the pages take ages to load. It doesn't matter what the page is, it takes ages, except that about: pages load fine, no problem. When I say pages take ages to load, I mean that everything about the page takes ages, not only the next, not on the images and other content etc, everything. This only started happening today and I only created a new profile a month or so ago. I don't have many tabs open (maybe 20) of which 9 are pinned. I do have lots of extensions installed.

I've tried troubleshooting/safe mode, that makes no difference.

Private browsing and loading another profile are fine, they don't have this problem.

I've cleared all cache and data, cookies, etc, including startup cache.

I've deleted the content-prefs file, and removed places files.

I've tried disabling and enabling hardware acceleration.

I've tried disabling TRR.

Probably some other things too, but so far nothing has worked.

Suggestions please! :)

I view a lot of pdf documents via firefox, the light gray background makes my eyes and head hurt after prolonged usage. In the past I found a solution on this forum that advised to set pdfjs.viewerCssTheme to "2" in about:config. This set the background of pdf viewer to black/dark gray. This has worked for years until recently when the pdf viewer switched to light mode again (pic 1). I checked the about:config settings for pdfjs.viewerCssTheme but there appears to be no change. I tried restarting the browser, setting the theme to 0 and to 2 again, updating browser. Sadly the theme is still light gray. Is there a way to change it again? The desired outcome is in pic 2. I do NOT want to change the color of the pdf pages themselves.

Hello

I got a new Asus Vivobook Core i9 16G Ram I did the basic Windows 11 installation for the Laptop and installed TotalAV.

After all Windows 11 updates passed, I wanted to install FireFox anf got this issue: Firefox cannot start correctly (0xc0000022) after version ..

I tried several time to close all Firefox task, uninstall, remove all files from existing profiles (local, roaming, etc...) so as all files under "Programs"". I made sure to get the latest code, but I always get back to this issue.

While opening FireFox, I immediatly get a Crashed Tab reported. Even the Settings are not opening in a Tab.

I even tried to use a older version. Same issue... Never the less I can Update the older version in "About FireFox".

After update I see 122 installed

I used FireFox for many years, and wanted to continue.. In the meantime I installed Opera

Any help is appreciated. Thank you in advance Laurent

Hello

```

~ /Applications/Firefox.app/Contents/MacOS/firefox-bin

[1] 5919 killed /Applications/Firefox.app/Contents/MacOS/firefox-bin ```

Can't event imagine how to debug this - FF has stopped working totally from the command line, despite options etc It is still working when run from the dock however. But I need to start it from the terminal for the second profile

With 'Back up your Firefox data' it says it saves all open tabs.

What is meant by 'open' tabs? Is it tabs that I have clicked on during my session?

I have just over 300 tabs, will Firefox save all of those tabs in the cloud or only the tabs I clicked on during a session?

I know this is an ongoing issue but it seems like nobody has mentioned it in a while so I figured I would stir it up again. I am fed up with the bookmark double spacing and having to scroll down all of the time.

If nothing else I would think that the Firefox team owes all of its loyal users an explanation as to why they don't seem to want to fix this probem.

Thanks my rant for this year :)

I used Firefox's saved logins feature for years and had over 100 logins saved on my laptop. I also use Firefox on my IOS phone.

After an update (I don't know which one, updates are frequent), the app on my phone stopped showing my passwords for most of my accounts. For example, in the passwords section of my Firefox IOS app, it would show the names of the over 100 websites I had saved logins for, but would say there was nothing saved as an email/username or password, just empty boxes. There were 8 logins for accounts I had created on my phone, and those ones did display.

I eventually got tired this and tried to sync my account so I would have all of the passwords I saved on my laptop and on my phone, but Firefox, instead of combining the over 100 logins on my laptop with the 8 logins on my phone, removed all of the over 100 logins I had saved on my laptop and replaced them with the 8 logins that were saved on my phone. My phone also still has the 8 logins.

Now I am missing most of my logins, including the email accounts I used and passwords. This is a big issue for me because I've used multiple emails across my accounts. Resetting all of my passwords will be impossible, and I need to access the over 100 saved logins that are no longer on any of my devices.

I followed the instructions in the "Recover user data missing after Firefox update" support page. The only other profile that showed up for me has no logins saved at all, so that's a dead end. I read other pages about "wrong way syncing", but its too late for me to try to tell Firefox my laptop was the master account because the damage is already done.

I need to know if there's a way to recover my profile with all my accounts. Please, share any information that could be helpful. I need it badly.

Hello,

I am using the Flatpak Version of Firefox on Manjaro Linux. I have hardware accelerated video playback on Youtube for VP9 but not for H.264 on YouTube and Twitch. I can verify that with intel_gpu_top. My hardware should be capable to do hardware decode. You can see in the provided screenshots, that it should work from the configuration standpoint. Do I missing something here or is this maybe a bug? I can provide any further information if needed.

I am running Firefox 121.0.1, which is currently up to date, on a slightly older MacBook, which has the latest MacOS it can get: macOS 11.6.8. As the title states, YouTube is almost unwatchable on my machine. The video will pause frequently while audio continues, motion is not very smooth, which is especially noticeable watching sports, etc. I cleared cookies and cache, I have run in Troubleshoot mode as well as tried flipping some switches in about:config that I've seen in YouTube videos and forum posts about similar issues, but nothing has solved this issue.

YouTube in Google Chrome works fine, and I've been watching HD YouTube on this laptop with it for years without any issues, so I doubt it has anything to do with machine specs like RAM, CPU, etc.

I was hoping to make Firefox my new browser and start supporting browsers that aren't chromium based since Google Chrome is going too far with respect to privacy and the freedom to use the add-ons I like (e.g. adblockers like ublock origin), but so far I have not been enjoying Firefox for YouTube. Any help would be greatly appreciated.

Okay so I just installed firefox to a new desktop and it synced up my extensions, passwords and bookmarks (minus bookmark icons/favicons which was solved simply by clicking on the bookmark in the toolbar and then firefox did the rest, kind of annoying but no problem)

Otherwise it seems all my browser settings, including settings I have done in the about:config have not been restored. I was under the impression that syncing firefox will sync browser settings and about:config settings but apparently thats not the case?

Is their a way to do that? I am less concerned about firefox settings as I can just screenshot a few pages no problems but I made many changes in the about:config that I am not sure I remember what I changed and theirs a million settings to change there so its not possible to recover that unless their is a recovery tool in firefox.

Again sync does not help here I need something more "robust" if that makes sense.

I've been having this reoccurring firefox bug every couple of months where randomly all audio from the application stops working is no longer available in the volume mixer of windows 11 (see example screenshot with twitch tab in background playing)

In the past, I was able to fix this issue by simply restarting the audisrv service and everything would work normally but now nothing I do seems to work. I've tried:

- Resetting - Uninstall/reinstall - Disabled all extensions - New profile

I do not have this issue on firefox dev or firefox nightly. If anyone has any ideas on how I could resolve or better diagnose this issue it would be much appreciated! TIA
