Firefox Community Forum

I'm having trouble with my bookmarks. I accidently included Firefox when using a program to clean up files from my PC. It wiped my bookmarks but I've managed to locate the backup html in my profile folder. Unfortunately I can't find anyway to actually use that back up. All of the guides I've found take you through the manage bookmarks tab but everything there is baisically unresponsive for some reason.

Is there any setting that allows to get rid from this annoying Titlebar (line with buttons) in fullscreen mode? So that it never shows up even when hovering the mouse pointer over the top edge of screen. When it jumps out everything slides down and always leads to miss clicks when I try to select tabs. I don't want it to be constantly present here as well because it takes up screen space.

Recently my AdBlocker extension in Firefox was disabled. At first I thought it was just a bug, but after I closed and restarted Firefox, it was still disabled, installing various other ad blocking extensions was thwarted by Firefox claiming these extensions are corrupt! I tried other approaches, including installing from github and from third party extension library; all are stopped by Firefox. I checked Firefox update, it claims that the latest version I can upgrade to is v127 (I'm using v126), so I think it's not due to Firefox not up to date. I spent a lot of time figuring these out, most pointing to Firefox banning Chinese users from using ad blocking extensions. After all these frustrations, I updated Firefox to v127, thinking updating to the latest version won't hurt, and these extensions are still disabled, installing ad blocking extension is still not successful. But somehow I checked whether I'm using the latest version, and BAM, I can now upgrade to v136. After the update, all these problems were solved. IF ONLY Firefox can provide some useful info of why my extension is now disabled, and why installing extensions are not successful, it would save me a lot of time and trouble. You dumb lazy people!

Dear sir or madam,

Can you please help me with a deeply frustrating problem I'm having with Firefox? After the last update, the shortcuts on my FF homepage disappeared and I can't restore or rebuild them.

Under settings, the homepage is set to show two rows of shortcuts but none are visible. I changed it to show more rows, closed & restarted FF, but no shortcuts appear. I then changed it to no rows, closed & restarted FF, then set it back to two rows, closed & restarted FF - still no rows. I've tried starting FF in troubleshoot mode, but to no avail. Looking through the Community Forums, I can't find anything that directly relates to my problem. In case this may help, I've had this problem once or twice before but I'm afraid I can't remember how it was resolved or if it was anything I stumbled upon that fixed it.

The environment is FF version 136.0.2 (64-bit) on an Acer Aspire E5 PC running Windows 10 Home, 64-bit, version 22H2, last updated 16 March 2025.

If you can offer any suggestion how I can resolve this and stop me pulling my hair out (in my case, it's an endangered species!), my remaining hair and I will be eternally grateful.

Yours faithfully, Peter Palmer

After usual PC restart non of my logins work anymore. I have logins.json file and key4 db file in my profile but firefox does not want to read them anymore. In json file I can see all the website and encrypted passwords, so all looks good there. Even more interesting, if I create new password it is saved in the same logins.json file but I can see those in the browser. So out of 50 logins there I can see only most recent two.

I tried to uninstall and reinstall mozilla and then copy logins.json and key4 files to the new profile but it did not help. Any ideas appreciated.
