Firefox Community Forum

Several times now I've closed firefox while having the open previous windows and tabs on startup on only for all my tabs to have been closed (with this time in particular being annoying due to losing tabs that I needed to have the specific link for). Is there any way to restore tabs lost in this way?

I am experiencing an issue where Google.com (other google domains work fine) will not load in Firefox, resulting in an infinite loading loop. Other browsers on the same system (Brave) work fine.

Here are the steps I have already tried:

Reinstalled Firefox completely

Removed Firefox via sudo apt remove --purge firefox -y

Cleared all user profiles and caches: ~/.mozilla/firefox, ~/.cache/mozilla, ~/.config/Mozilla

Reinstalled via Flatpak

Tested network connectivity outside Firefox

curl google.com works correctly

DNS resolution works via getent hosts google.com in the host system

Checked proxy settings

Ensured “No proxy” is selected in Firefox → did not resolve the issue

Tested in Safe Mode (disabling extensions)

Problem persists, so not caused by extensions

Tried disabling IPv6 inside Firefox

network.dns.disableIPv6 set to true → no effect

Cleared DNS cache inside Firefox

about:networking#dns → clicked “Clear DNS Cache” → no effect

Disabled DNS-over-HTTPS (Secure DNS)

about:preferences#privacy → “Use secure DNS” → disabled → no effect

Disabled HTTP/3 (QUIC)

network.http.http3.enabled set to false → no effect

Verified Flatpak network permissions

flatpak info --show-permissions org.mozilla.firefox shows network access allowed

Inside the Flatpak shell:

flatpak run --command=sh org.mozilla.firefox getent hosts google.com

→ returns only IPv6 address: 2800:3f0:4001:839::200e google.com

Since the 145.0.2 update web pages are loading very sloooooooow. Also, images are loading very slowly, if they load at all. At the start pages would not load at all then about a week they started loading but very slow as mentioned. Any ideas/help will be very much appreciated. I am using Windows 11.

Is there going to be a native PWA for Firefox on Linux? I really would love to have it. I use Ubuntu on my laptop and really don't want to use a chrome browser or some weird workaround.

Crash submitted, ID = 320cc808-4505-4cba-6e0f-9f2c2955d007 Still happens in troubleshoot mode.

Hi! I have seen that Mozilla will be moving forwards with integrating AI to Firefox. I am very uncomfortable with this, as AI poses a risk to the privacy and security that made me choose Firefox in the first place. If this is the case and AI is truly integrated (at least without an option to turn it off or opt-out completely) I will no longer use this browser and switch to something else. I enjoy Firefox so I am hoping that this will not be necessary....but we will see.

In Windows 10, I could open Manage Bookmarks with one mouse click on Manage Bookmarks on the Bookmarks toolbar, and the bookmarks would open at the top of my organized list, with the Bookmarks Menu already displaying. One click! Fantastic!

Now, in Windows 11 I am unable to open Manage Bookmarks on the toolbar, as it doesn't exist, and does not exist in the Customize toolbar display either. Instead I must click on the "Show Your Bookmarks" icon on the Bookmarks toolbar, then click on Manage Bookmarks, then must scroll the results to the top, then click on Bookmarks Menu. This procedure, compared to how simple things were with Firefox, using Windows 10, is a real waste of valuable time.

Is there any way to open Manage Bookmarks, with Bookmarks menu displayed, with one click of an icon on the Bookmarks toolbar, as was the case with my Windows 10?

I opened a profile that I had just used recently to a blank tab bar. I closed it and the sessionstore-backup folder did not have a recent backup, The most recent about a week old.

Just for testing, I tried to restore with one of the upgrade.jsonlz4 file, about 2 weeks old, but it also had no session. I then restored one that was 2 months old. That one had a session

Now, Firefox no longer generates the upgrade.jsonlz4 files

For the past few days, I haven't been able to use Google Lens for searches. Why? It used to work, and I haven't changed anything on my computer.

I read the support article about this problem: everything seems fine, Google is definitely my search engine... Can you tell me what I need to do to get it working again? Thank you

Doing a "find" ends up showing a greenish (so I'm told) background with white text. Want to guess which "find" in the attached image is difficult for me to find?

What I would like: Find (focus): yellow text on black background Find All: white text on black background

Yes, of course it would be nice if that would auto switch to black on yellow if the website default is black background.

I can hack userContent.css and get the selection function to work:

/* General highlight (for text selection, etc.) */

selection {

   background: #FFFF00 !important;  /* Yellow background */
   color: #000000 !important;       /* Black text */

}

I can hack userContent.css and get the Find All (sans the focus) to work.

But firefox always provides the focus with white on green. Even if I do something like this:

/* Customize the color of highlighted search text */ input[type="search"]:focus::selection {

   background: #FFFF00 !important;  /* Yellow background */
   color: #000000 !important;       /* Black text */

}

I tried several themes. No change. I tried changing Windows Preferences. No change.

There must be a way to make this "find" feature useful for me.

When using Firefox and clicking on a link oftentimes instead of the link opening in Firefox it opens Microsoft Edge. I have Firefox set as my default browser. Other than uninstalling Microsoft Edge is there any other solution to this problem? My OS is Windows 11 Pro.

I am not able to receive mail from a user sending me mail from a gmail.com account. I have communicated with my ISP Optonline.net and they state the there mail process "checks out" and the issue could be the browser I am using, Firefox. The last email I have from a gmail.com sender was 8/28/2025. I have asked two different gmail users the send me mail and have not received any of them. I have cleared the Firefox cache but that did not correct the issue. I come to you to figure this issue out and hopefully solve it. Thank you Richard Everett [email removed]@optonline.net [phone number removed]

Some websites won't load at all while other are very slow to load but some will load just fine, example Crunchyroll (screenshot attached) won't load at all its just spinning loading icon and a white page but if I try it in a different browser it works just fine, but with Youtube it will load but is choppy and low quality videos and same thing as before I load it in a different browser and no problems. I have tried every possible solution I can find from clearing cookies and cache to refreshing Firefox even scanned for malware and virus nothing has worked please help me figure out what is happening and why it's only with Firefox that I am having this problem and its not hardware can play online just fine and download games from steam perfectly fine.
