Firefox 技術支援討論區

As from v100.0, Firefox allows users to "set their preferred color schemes for websites".

Ironically, this does not addresses complaints from users, including me, who wish for a consistent Light theme all across Firefox.

Even if "Web site appearance" is set as Light, the following still remain dark:

• Background of main drop-down menu (Containing "Sync and save data", "New tab", "Print", "Settings", etc)
• Background of right-click menu (Containing the refresh icon, "Save page as", "View page source", etc)
• Background of "Please enter primary password" menu
• Background of auto-filled user name and password menus
• Background of elements in a bookmark folder
• Background of Downloads menu
• Background of Print menu
• Background of "Clear all history" menu
• Background of "Find on this page" menu
• Background of "You are about to close X tabs" warning menu
• Colour of title bar for "About Mozilla Firefox" window, when the window is not currently active

Being able to set "browser.theme.toolbar-theme" permanently as 2 would fix all of the above, but users are still (Note: Since v96.0, when this complaint was raised) prevented from doing so. Why?

Each time Firefox updates, the email client changes to the outlook default. The last 2-3 updates, mailto does not appear on the file,settings,applications menu. Nor will it populate if I type it in. I have tried every instruction to no avail. I am a long-time firefox user, non-techie and it is discouraging when things disappear with each update lately. Would appreciate any suggestions. Thanks

So this morning (5/4/2022) I start the computer (desktop) Win 10 Pro, 64 bit and Firefox will not connect.

Checks: I verified that my phone connects to my wireless; I verified that email is connecting; I verified that Chrome is connecting.

I did the following:

I refreshed Firefox -> Firefox will not connect I started Firefox in troubleshoot mode -> Firefox will not connect I uninstalled and then restarted my computer and then reinstalled -> Firefox will not connect

Further, the once working about:config update to reinstate compact menus has no effect (why not test for a mobile OS before expanding the menus...?) Regardless, this secondary for the moment.

What to next is a mystery to me. Firefox has become so troublesome that it is almost not worth it to continue fighting with it.

I just installed firefox on a linux machine, and spontaniously, I keep getting a message pop up toward the top of the screen saying: "To play videos, you may need to install the video codecs".

This occurs when I am not even trying to play videos. I can play youtube videos fine. I don't need to install anything. It normally occurs when I am checking my outlook email, but can happen at any time.

So my question is, how do I stop this message from coming up? Prefereably WITHOUT installing some codec that I do not currently need.

Another message that comes up is an offer to install an outlook extension to my browser, but this is triggered by opening outlook email. I have no need for this either, so it would be nice to get rid if this message popping up as well.

Thanks

Hello, I just installed windows 10 on my nephews computer. I installed firefox so I don't have to use edge, but firefox won't start. It just flashes. I have tried re-installing firefox, deleted all mozilla and firefox files and folders and clean installed firefox, even reinstalled windows. Troubleshoot mode don't work, it just flashes too. I checked for Crash Reports, but there are none. The only time it works is when windows is in safe mode, I even upgraded to computer to windows 11 hoping that it would fix what ever is going on. But it didn't. I honestly have no idea what to do next. Firefox has worked on that computer before. Everything else works fine, it's just firefox that won't work. If anyone has any ideas, please let me know.

Before update when I clicked in PDF viewer toolbar download button it opened a screen to open with, right now it only download a file. I want it back. I have firefox as pdf viewer, but sometimes I need to open file with Acrobat DC, that's when I did click download button. It works on other computer like before, it is before firefox update.

I can only save (not open) Gmail attachments after the latest update and JPG is not showing up in my the Applications section of Settings/General so I cannot fix it.

This has happened one time too many guys, every update but this time half the items I would normally get as an attachment are no longer listed in the applications menu.

If I cannot get a fix quickly I will be forced to move to Chrome (which I REALLY hate the idea of). I see 25 - 80 emails a day and it is mission critical that I can open and view email attachments without having to save them.

A little help??

Downloaded the latest version of FireFox, and have somehow lost the toolbar for my bookmarks. Have tried suggested things mentioned that i can find to no success. How do i get this much neede item back, HELP please?

My google drive keeps disconnecting, and google drive/google docs links are not working. I have attached a screenshot of the new tab page when I copy paste a google sheets document URL into the search bar and hit enter. After the reloading icon animates, I stay on the new tab page and the url just sits there. The debug console shows 1 GET request that is timed out (picture also attached).

I can fix the issue by completely closing all firefox windows and opening again, but it will disconnect me after some minutes.

I got an email to update to version 100, and downloaded and installed, but now I have no bookmarks or anything else, just a blank version. Please help me! Thankyou!!

This is more of a convenience issue but the new download panel pop-up from the download arrow is very distracting. I couldn't find an option to turn it off so I had to go into the config and turn the true flag false for this "improvement". Is there a better way of disabling this pop-up and if not will there be in future versions of firefox?

Hey, I can't add new filetypes to the handlers.json Who had this before? I have already reset Firefox, deleted handlers.json, used safe mode... all without success For example, when I click on a ZIP file, the "save as" menu opens immediately. In the FF settings this filetype does not appear. So I can't define how to handle new files. I have also tried the addon "Content-Type Fixer Content-Type Fixer".

It seems since Firefox 100 the address bar has taken to being white-on-white, making it nearly impossible to read. There isn't any issues with light themes. It doesn't matter if I change the Windows 10 default app mode to light or dark. Light themes have black text on white background, but dark themes have white text on white background. Any ideas?

When i have like 50+ tabs pinned then firefox breaks and we cannot scroll tabs anymore. Of course closing tabs doesn;t work with Ctrl+W, but then we need some different shortcut for closing pinned tabs (like for example Ctrl + Shift + W) or just you fixing this bug ;) I attach 2 screenshots that show what happens with Firefox when having too many tabs pinned. I can't navigate through tabs anymore.

I have recently updated to Firefox 100. I am now getting this message on a page "You are using an outdated browser. Please upgrade your browser." I have confirmed I am up to date.

The "update you browser" has a link to "whatbrowser.org", which I believe is run by that horrid business, Google.

Has anyone struck this problem? Is there a solution?

I have closed Firefox & re-opened, I have rebooted the computer. No change.

I was trying to solve a hanging issue with firefox and following a 'tip' I changed the name of places.sq.lite to places.sq.lite.old I figured the renamed file would be there to back-up from if something went wrong and although the hanging issue seems to have been fixed I have lost hundreds of links that have taken ages to put together.

Where is sq.lite.old located as it is missing from the original folder? It is not in my recycle bin so renaming it to old hasn't simply deleted it. In another folder there are bookmark backups with dates (JSONLZ4 files) but I have no idea how to get my old links back from them, if indeed that is what they are for.

Please help.
