Firefox Community Forum

I have used the OneTab browser extension for years. Mac computer ran out of space but was completely backed up. Got new computer. copied Firefox profile from the and updated the profiles.ini to use the backup data.

I used a backup dated 12 Feb 2026.

I was able to restore my bookmarks and passwords from this profile, but they seem to be from many years ago. I was not syncing to my Firefox account and saving the passwords to my computer. i assumed they would be in a bakup. None of my OneTab items were restored.

I wonder if part of the problem is that Firefox wants to ( and did) update my new computer to Firefox 145 or 147. I don't know which Firefox was running when I had the issue but I suspect it was older.

All of the storage/moz-extension files are there and firefox is using the correct profile data. Is there any way to find/read/extract the OneTab history? Where should I look? I contacted OneTab and all they could tell me was to look in storage/default/moz-extension.. ( nothing readable there) Thanks

The `Passwords` page can not show any username and password. But the firefox can still fill usernames and passwords automatically and remenber new passwords. I can export data via menu (right-up) too.

Many websites that I use regularly, such as Zillow, no longer work correctly in Firefox ESR (115.33.0). The top menu in Zillow disappeared this week. Others work, but all the text is greyed-out. All except the text thing seem related to Javascript features. For instance, check boxes on a Wordpress site that I manage quit working last month. Some, like www.RCgroups.com just sit and spin, and never fully open up.

But they all work fine on an old copy of Chrome (109.0.5414.120), that is no longer supported on Windows 7 and hasn't been updated in probably 3 years.

My only plugin is NoScript, but the problem is the same whether it's turned off or not. And I also use NoScript on Chrome.

I use Win7 for the same reason I use Firefox -- it is safer, far more stable, faster, and it doesn't force updates on me that invariably break things. I appreciate that Mozilla has extended support for the last stable version of Windows. But somebody should look into this growing compatibility issue.

I recently started to get a"The security sandbox is disable" warning. I have already gone into about:config

my settings:

Content Process Sandbox Level 8 Effective Content Process Sandbox Level 0 (note in about:config this setting is 6?) Win32k Lockdown State for Content Process Win32k Lockdown enabled -- default value is true GPU Process Sandbox Level 1

Firefox ver 145.0.2 (64bit)

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.

Hello. For years I've been successfully using your browser. Now it keeps giving messages that say "Try Again" .

I don't know who thought it was a good idea to put someone who is pro-AI in charge of the anti-AI browser. I'm on Firefox because it doesn't use AI. You want to add in the most foolish, expensive, environmentally destructive, money sink that none of the userbase wants? Fine. I don't have brand loyalty. You choose personal wealth over the health of our environment and community by shoveling AI stupidity at us, I will drop this browser like a lead weight and switch to the lesser known browsers. I hear Waterfox hasn't bought into the slop yet. Might be time to change over to a more mindful system.

The lack of a title bar makes it impossible, for example, to close the application by pressing the "X" icon in the upper right corner. The title bar does not appear when the application starts, but does appear when the application window is minimized and then maximized.
