Firefox Support Forum

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?

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?

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 :)

How most of the the "serious" articles of those recommended come from moderately left to very left sources. The well-intentioned but hopelessly misguided (and often destructive) selections from the NYT, Atlantic, Vox, New Yorker, etc. are of little little interest or use to me. Please consider articles and opinion pieces from the WSJ. American Spectator, NR, etc. as well. You might just increase revenue and profit. Thanks! Ted Alpert

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?

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.

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.

Edit: grammar mistakes

basically just the title. In the last couple days youtube.com specifically has been borderline unusable for me on firefox. All other websites work fine for me on firesfox and youtube has no issues on other browsers.

Starting this morning I suddenly cant delete or mark emails as read in Outlook.live.com. Even if I open an email, and it appears as read after that, if I refresh or leave the page and come back, its marked as read again.

I tried dropping all add-ons (a kill switch to drop all add-ons and re-activate them is still a feature I feel Firefox needs, I have to click every single one of them every time) to no avail.

I was in the process of writing this question on the Microsoft forums (which is usually like whizzing in the wind) when I thought to try a different browser. I had zero issues and Outlook.live.com worked perfectly normal on Microsoft Edge.

This HAS to be a bug in a recent update in Firefox

From 8 years of using Firefox and updates, there is a perpetual, never-ending serious bug, occurs on all computers! If one has a lot of open tabs with a lot of RAM, the tabs are also automatically frozen then it is impossible to add bookmarks to all 4760 tabs. So never ever make a bookmark! It takes forever to work, nothing happens, even no extension can, nothing will help. This is some kind of stuck bug. Chrome, it ALWAYS, ALWAYS WORKS WITHOUT PROBLEM! I can add in 1 second in Chrome, but never, ever in Firefox for 8 years!

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! :)

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.

Hello

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
