Firefox 技術支援討論區

I have been using the FF dark theme for a while now and am used to it, but I do not like other websites dark (for example youtube, ietf documents, etc.) and suddenly firefox has started showing them in dark mode as well. I have tried to search for a fix for this with no success so far. What I have tried so far: set ui.systemUsesDarkTheme to 0 set browser.in-content.dark-mode to false

Please help me disable Firefox requesting dark websites while I still use the dark theme itself. Regards.

I noticed the toolbars had changed positions and thought I'd use the customize page to see if I could reorganize them. Somehow I ended up with the usual three toolbars, but bookmarks are on the top (tabs) toolbar, not the bottom (bookmarks) toolbar, which is empty. This is Ubuntu 21, firefox 95.0b2.

Top: Starting on the far left are the Ubuntu window controls, my bookmarks. and tabs. Middle: The customized URL/search bar. Bottom: The bookmarks toolbar, which is empty. I know this is so because CTRL-SHIFT-B hides and shows it.

I can drag bookmarks on the top(tabs) toolbar around, reorganize them, and and delete bookmarks and folders, but always only on the top (tabs) toolbar. I cannot drag any of them to the bottom (empty bookmarks) toolbar.

Great news about Firefox being added to the Microsoft Store. It seems to me that method of keeping Firefox up-to-date might be more effective than the traditional Mozilla background service. However, I use the Beta channel. Is there any chance that channel will be added to MS Store? Regardless of the version I assume that you have to completely uninstall the conventional Firefox install and lose all your about:config and other settings (anything not included in Sync).

So, certain web pages apparently have text in white font color while also using a white background. I'd blame it on the team behind the page, but it seems that it works well on Chrome, so I'd like to know how to fix it.

I'd add images, but they take way too long to upload

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)
