Recently I upgraded my Windows 10 to Windows 11 and since doing so, I've had consistent errors while browsing the web on Firefox. Most notably the "Humm. We're having trouble finding that site." error message.

For example, when visiting, say Verizon.com, the tab will display the aforementioned error to which I press Try Again and the website loads correctly every-time. No hiccups on the refresh.

I've tried the following:

1. I've performed a completely clean uninstall of Firefox and then reinstall
2. Cleared all browser history/cache
3. Removed all extensions
4. Disabled IPv6, HTTPS Over DNS, No Proxy
5. Ran through Firefox's troubleshooting
6. Used Firefox Troubleshooting Mode in the Browser
7. Tested that the problem does not happen while using Edge

I've never had a single problem on Windows 10 with Firefox. Curious if others are experiencing the same issues and if there are any fixes. Nothing else on the PC has changed.

• Windows 11 21H2 2200.348
• Network driver is the latest Win11 edition
• Firefox 95

I used Apple Migration Assistant to move the entirety of my wife's old iMac (the old computer won't accept updates, so her machine was not secure) to a new one. The migration operation appeared smooth and essentially perfect.

Somehow my Bookmarks have overwritten my wife's (years ago, I turned Synch = ON, was that it? Synch is OFF now). The bookmarks are still OK on the old computer, so how do I locate and move that info to the new machine "AND BE SURE TO GET IT RIGHT"? My wife is the family business manager, so her bookmarks are Insurance, Banking, Healthcare, etc.

I've done some searching, but there are thousands of posts, I can't wade through all of that.

I just updated to 95.0. I use default Firefox home page with the Search bar. The background turned to black with this update. The background has also turned to black for some of my bookmarks or sites I go to. Settings, Language and Appearance, Colors, Text is Black and Background is White. I have never changed that. How do I get the background back to White?

As I described in my subject, I can't download ANYTHING through Firefox, unless it's in troubleshoot mode. I know that troubleshoot mode disables multiple things, including all of your themes and extensions and add-ons. For example, I can't open my own files in my AOL or Gmail email and download them. I also can't download things from my Google Drive. (Unless I'm in troubleshoot mode.)

However, thinking that it must be one of my add-ons, such as my adblock or any other one (and I mostly just have an adblock), I opened Firefox normally and completely disabled all of my add-ons, but that did not fix the problem.

I also tried downloading things while I had my Antivirus briefly paused, but that didn't work either.

The only time I can download things is in troubleshoot mode, and I don't know what's causing the problem.

Since I upgrade MacOS to Big Sur, a couple basic Firefox functions have stopped working. 1) History is not being saved. I can restore deleted tabs, but there is nothing in the History menu, nor is there any record (for example, in the form of auto-complete) of websites I have visited in the past. 2) My bookmarks file appears to be mostly read-only. Clicking on the star icon to save a new bookmark does nothing. Selecting Bookmarks > Bookmark Current Tab does nothing. In the Manage Bookmarks environment, selecting Add Bookmark from the gear icon brings up a dialog box in which the only content is a Cancel button. In the Manage Bookmarks environment, I can change the Name of a current bookmark but cannot change its URL. If I try, it reverts to the old URL as soon as I click away from it.

The current help page that most closely describes my symptoms is https://support.mozilla.org/en-US/kb/changes-toolbars-and-window-sizes-are-not-saved. I tried both remedies, including refreshing Firefox and deleting xulstore.json, but no change in symptoms.

For some reason, all of my Firefox related things have switched to a dark mode. My DuckDuckGo page switched to dark, my tab groups have switched to dark, my links have switched to dark! This happened when I was using the Dracula Dark theme, and the Lush Bold Theme.

Bing somehow auto default set as my search engine and i need google as my default. when i drop down menu to change it gives no options, it only says "a browser" with Firefox logo next to it. i need help to fix this issue please! tyia:)

I'm running a late 2017 MacBook Air with memory of 8 GB 1600 MHz DDR3, Monterey 12.0.1 and using Firefox 95.0. I am having a continuing issue with a web site (E edition of The Fort Worth Star Telegram) that after opening a second page/window of a news article, that 2nd open page causes Firefox to stop responding. Clearing caches and or restarting computer does not help. Feedback to Star Telegram has yielded no solution.

i need to remove the usernames from a drop down list on a particular website. same problem on microsoft edge, they have a trash-can icon beside each username in the dropdown list, so it's easy to remove each username. what is the equivalent on firefox?

Firefox updated automatically to v.95.0 (64-bit), Windows 10, on December 8, 2021 at 1:09 PM.

Since the update, all my Bookmarks are missing. All attempts to restore them have failed (using the Menu->Bookmarks->Manage Bookmarks->Import and Backup->Restore option). My toolbar settings are: Bookmarks Toolbar->Always Show and Show Other Bookmarks.

This is a critical loss for both business and healthcare purposes. I would appreciate an immediate and viable solution.

I've been using Elijah Lopez's Matte Black (Red) theme for months. Recently, I think because I added the ClearURLs extension or some other change, certain websites enter some sort of "dark mode" when accessed.

Websites that do this include Twitter, an independent blog, and Youtube.

The website appears normally with the default light theme enabled. In the second photo, the website appears in the "dark mode" with the black Firefox theme enabled.

I have deleted cookies and cache, reinstalled Firefox, and reinstalled Extensions. I think this problem only occurs with dark themes, and nothing else. The moment I change to dark theme, the problem comes back. It is strange because the dark theme was working just fine for months until recently.

How can I keep the dark theme, preferably the same Elijah Lopez's dark theme, while using websites normally and not in this weird "dark theme" style adaptation?

Hi all,

Since I switched to Win 10 Firefox constantly crash on my computer.

• Tried fresh install no change
• Tried repair no change
• Switched off extension and then on (one by one) no change
• Deleted cache - History - etc .. :( it worked for only a few days since I did a full scan with Microsoft Defender.
• Since this last crash (as I could not launch Firefox anymore I used shift + click on Mozilla shortcut)I decided to switch off the graphic card acceleration and all the other option in this menu and it seems to help

Could you tell me how to send you the crash report ( I do have 8-10 of them already sent to Mozilla)

The documentation says to use F11. F11 was removed from ChromeOS. The Full Screen Button on the keyboard will take Firefox out of full screen, but when you try to use it to put Firefox in Full Screen, the window gets slightly larger, and then goes back to its original size.

Other applications seem to be able to go to full screen using the Full Screen key that are running under Linux. For instance, gvim, thunar, meld, and gnucash all will go into full screen with the Full Screen Key.

When I try to clear cookies and cache etc in Firefox 95.0 on my Mac (OSX 11.6.1), there always remains 811kb, no matter how many times I try and clear it. Deleting the Search history doesn't get rid of it either. Previously, this didn't happen. What's going on please?

My background color is black, even though I have it set to white under "fonts and colors". Text is set to black, and background is set to white. But the background is actually black. I don't know why it is black when it is set to be white. Thanks for any help.

After updating Firefox to v95.0 (64 bit) websites start to shown in dark mode.

My windows theme is dark, but i don't want to use same for Firefox. I tried to set ui.systemUsesDarkTheme value as 0 in about:config. But problem still remains.

Is this a bug with new version, or a feature :)
