Firefox Support Forum

The option to restore tabs and windows is no longer working for me. I normally have a dozen tabs I work thru every day. Yesterday when I shutdown Firefox, all those tabs were there. Today when I open Firefox it only had to single Firefox default homepage. Checking under History there is no option to restore previous tabs, and the recently closed tabs was empty.

To test, I opened an IMDB page and pinned it. I then went to Wikipedia. This gave me a pinned and unpinned tab. I shutdown Firefox via the "X" to close the window. When I restarted Firefox there was only the default homepage. Neither IMDB nor Wikipedia showed up under recently closed tabs and no option to restore the previous session was available.

I have operated Firefox this way for several years. I don't know why this behavior is no longer being supported.

I just installed a fresh copy of Windows 11 and last Firefox, and get some weird rendering of letters on some websites. It seems that the end of a letter is bolded so to speak (screenshot attached). Also, there is an unnatural widening between the lines of text on the same websites (screenshot attached). This does not appear on other browsers. What can I do to correct it?

After a recent reinstall Firefox seems to have a problem. This seems to be only Firefox specific and I can't find a working solution online after googling.

Youtube videos work, although they do give errors sometimes. A refresh always fixes those. However Twitch/Youtube live streams do not, and display a generic error message. When trying other browsers the live streams work fine.

And old Bugzilla post (https://bugzilla.mozilla.org/show_bug.cgi?id=1467495) describes what I believe to be a possible reason for the problem, however following the solutions in that thread have not yet lead to a solution.

Any further insight or solutions would be appreciated.

My mouse wheel does work when I try to scroll in any page. The scroll wheel works when I am scrolling though tabs but only if I am holding Shift or Ctrl. It also seems to work just fine in troubleshooting mode, but nothing else seems to work. This problem started just after Firefox updated to the newest version.

Firefox Developer Edition - Developer Console is killing my productivity. It started opening in Full screen mode about a week ago and will not exit full screen. I have to F12 and exit developer console. This is a major issue because, I work with the console not docked. Docking blocks my productivity. F11 only puts it into some very weird outline mode where all I see is a rectangular grey outline on my full screen. If I click on it, it repaints the console in full screen. There is no option to drag and expand or contract. Nothing. Nada. Please help. This is my primary browser, er -was my primary browser. I'll continue to work around it until my patience is completely exhausted. Almost there now.

Sorry about the terrible markup on the screenshot. It's hard to encircle a big gray full screen empty frame. Thank you.

Hi Since the latest update of Firefox, if I am clicking on a bookmark at the bottom of my bookmarks list, when I then access the bookmarks list again the bookmarks list always returns to the top, so I have to scroll down again to the bottom, as my bookmarks list is quite long. It never did this before and would always remain at the same point in the bookmarks list when I opened them. Any help would be appreciated. Thanks

Since Firefox 109 and 110 also you can not login to hidive.com. It just loads a blank page(empty source) but not logged in. Firefox Developer Edition does work. 110 and 111. Tested on both linux and windows without extensions and tested with tracking prevention turned off. I reported this after 109, but I could not find the report.

Hello all, When serving an animated HTML5 banner on Firefox the text or image is blurry Serving the same in Chrome or Edge is super sharp Attache is a sample showing the different results in each browser

Hello Firefox Support Staff,

I use Firefox on a Windows 10 desktop PC.

Firefox often crashes when I close the browser by clicking the X either at the top right or the tab.

Please let me know the type of information you need to debug.

Thanks, Sam

When going thru my bookmarks why does it jump to top of list when I go back to list. Very inconvenient when searching thru my bookmarks. Started with last update 110.

Hello. I was reading Quora.com web site on my notebook in Firefox (110.0.1 64-bit) normally, then I got power outage. When electricity returned and I tried to open it again, browser didn't open it and I gave me message:

Secure Connection Failed

An error occurred during a connection to www.quora.com. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem.

I've tried to get support from Quora.com how message said, but they told me "this error does not originate from our website". And gave me some suggestions - "The easiest way to fix this secure connection error is to reset the Firefox settings." I've performed "Refresh Firefox", but problem persists. I don't use VPN. Can anyone please help me with this problem?

I've been getting funny glyphs on my google engine searches. See png. Turning off add ons and reinstalling software doesn't seem to clear the issue.

The funny text when copied and pasted is revealed to be the actual text it was supposed to be.

This is very very weird... and its only on firefox, no issue for chrome or safari. Happened just a few days ago. Don't remember installing anything. Could be malfare from a font site?

Recently I've noticed that some sections in Google search results pages show black text on dark backgrounds when running dark mode.

It doesn't happen in private windows or in troubleshooting mode, so I suspect it's some obscure custom setting that's causing the issue. It also doesn't happen in other browsers.

I've tried switching themes and changing the colour override settings but can't find the setting causing the issue. I've also tried clearing the browser cache and cookies but no dice there either.

Hoping to avoid a refresh just to fix this.

It seems like almost every time I do a Windows Update on and sometimes when I just restart my Lenovo IdeaPad 3 my language gets changed from American English to French. Even some of the add-ons change preferences. Since I don't speak or read French it can be a real hassle to get everything changed back. What I usually end up doing is going to the page on the Mozilla site that has different downloads for different languages and I download the correct one. Once I install it over the existing installation things go back as they should be until I do another Windows Update or like I said before, sometimes after just a restart. This just happened again a few hours ago when I did a Windows Update. All the menu items and drop downs were suddenly in French. My Forecast Fox changed to Celsius instead of Fahrenheit. My Notifier for GMail changed to French. A couple log in pages for some web pages were in French. This never happened with other laptops I have had that were different brands. I once tried just uninstalling Firefox and then reinstalling the correct language version and things were fine until the next time I did an update. My preferences are set to how I want them and I just don't understand why it keeps getting changed.

I recently switched over to using an SSD, and I am trying to do everything I can to prevent unnecessary writing to that drive. I've already found instructions for moving the location of Firefox's Cache files to my secondary HDD, but I haven't been able to do the same for Cookies; they're still being stored on my C: drive, in the AppData folder.

Is it possible to change the path that Firefox uses to store Cookies? If it is possible, how?

FF 110.0 - Dropdown menu in responsive design mode will not display more than 20 devices, regardless of how many are selected. Does not scroll, as in earlier versions.

Roboform not working with Firefox version 110.0 on Windows 11. Works on Chrome and Edge. I've always preferred Firefox, but I'm very dependent on Roboform, so I'm migrating to Chrome until Firefox is able to see Roboform.
