Diễn đàn hỗ trợ Firefox

I have a home-built media center (OS: Linux Mint 20.3) utilizing Firefox as the primary browser. This system has run almost flawlessly for many years. Updated to 20.3 in early 2022. Rather suddenly (yesterday) Firefox began repeatedly crashing, displaying 'Mozilla Crash Reports' (example attached). Firefox appears to initiate as expected. However, on display (e.g., Youtube, Facebook, web page, etc.) request, Firefox immediately throws a 'Mozilla Crash Report'. I do not recall any changes to the system that might have generated this condition, and have spend most of today unsuccessfully troubleshooting.

MB: Gigabyte F2A85XM-D3H CPU: AMD A-10 5800K APU with Radeon HD Graphics OS: Kernel: 5.4.0.170 generic x86_64bits; on 128MB SSD Firefox for Linux Mint mint-001 - 1.0 (122.0 (64 bit)) RAM: 7 GB

I have attempted to follow some of the moz://a Support pages (i.e., "Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems"). I have noted that while in 'Troubleshooting mode', Firefox appears to behave as expected, seeming to implicate extensions, themes and/or hardware acceleration. However, under normal Firefox operation enabling/disabling these does not seem to resolve the issue.

    * Hardware acceleration (on or off) still results in display of 'Mozilla Crash Report',
    * Default theme is selected, and
    * I don't appear to have any unaccounted extensions or other addons enabled.

Any thoughts and/or additional guidance would be greatly appreciated.

I always use the current Firefox on two Macintosh browsers running OS 10.14.6.

Recently (in only one of the computers), if I download a file, a pane containing recent downloads opens in the upper left-hand quadrant. This is distinct from the downloads portion of the "Library" area, and gets in the way of my ability to use Firefox efficiently.

I can't seem to find a way to keep this pane from repeatedly opening up as I download things. Can anyone help?

I'm not very computer savvy but I followed a website a few months ago to edit Firefox so it'd default to dark mode. I think I went in and edited source code? I can't find the instructions anymore but I'd like to revert back to the original setting. How do I do that? I tried to refresh Firefox but it's still coming back with some websites in dark mode and some not. Please advise!

I've disabled this for my google account. So when I search from google.com this behavior doesn't happen. But when I type anything into my address bar on Firefox to search, the first suggestions are from my search history.

I don't want to delete my search history.

I often use my search history to find specific things that I need, but didn't bookmark at the time. I need my search history to be saved. I just don't want to automatically receive suggestions based on it.

Is there any way to turn this off? Even with an extension or something?

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?

I've just updated to Firefox 125 and now, when I start to type in the URL bar and get my suggestion dropdown of previously visited pages, I no longer can see the actual url for each entry. All I see is the top level name for each entry.

This is not helpful, as I may have perviously visited a number of pages on that site and the information shown does not give me a way to differentiate sufficiently between those pages.

How can I get the exact url displayed on the suggestions dropdown.

How can I get those top level descriptions NOT displayed, so that only the urls are shown?

Hi, I develop a firefox kiosk application for an IoT device and I'm wondering what setting disables this message?

This message popped up on a release of our software which hadn't applied a policies.json file yet, is it safe to assume it will be covered by the following policy which we have on a later release?

   "UserMessaging": {
     "WhatsNew": false,
     "ExtensionRecommendations": false,
     "FeatureRecommendations": false,
     "UrlbarInterventions": false,
     "SkipOnboarding": true,
     "MoreFromMozilla": false,
     "Locked": true
   },

After the latest update (124.0.2), two of my add-ons (Tapermonkey and Youtube Redux) are not working, even though Firefox says they're enabled, and it is giving no indication that the add-ons aren't working, no pop-ups to enable some permission for these extensions. Both of them reformat the layout of websites to make them more usable, and using sites without them is basically impossible for me. I have tried:

• Restarting Firefox
• Disabling the add-ons, refreshing, enabling the add-ons, and refreshing again
• Checking for add-on updates (everything is updated)
• Deleting and reinstalling the add-ons
• Restarting my computer
• Checking the permissions in the extension menu
• Turning off all other extensions except for one of the ones with issues
• Reading through the FAQs and help pages and following the instructions on some of them

Nothing has worked. Every time I reload one of the sites affected by this to check if it's finally worked, the site takes a very long time to load. Since these add-ons are for different websites and both aren't working, I know that the problem is not with the sites themselves. Thank you.

I have 2 questions after the upgrade ( If that is what they call it). #1. Getting all my apps re-setup , I noticed that some were not showing up on the bar to the right of my search bar. #2. When I open FF it only opens with a half page on the left. This next jusy a polite general question. After the uproar about fvd suspension, why did FF feel the need to do it again? What I mean is why did they wipe out All my apps and deleted other programs I had BOUGHT and now having trouble getting downloaded again when they were working perfectly before 100? Are these programs also considered "Dangerous". Sorry. Could you give me an approved FF alternative to FVD and I don't mean this piece of garbage that is on your web page. You wanna throw something against the screen every time you look at it.; UGLY!!!!

Within the Add-on Manager by clicking Manage Extension Shortcuts - you can make shortcuts for add-ons to perform specific functions via the buttons on your keyboard, but I want to actually be able to use the buttons on my actual mouse rather than the keyboard.

Does anybody know if this is possible? Currently when I try to use my mouse to input a 'shortcut' in the 'Type a shortcut' box nothing works.

Are there any about:config settings or add-ons that can enable me to use my Mouse to make shortcuts for my add-ons?

tell me how to undo "troubleshoot mode", read the "help" article, do not understand.

tell me how to undo the "More from Mozilla" in about:preferences. I have NO idea.

I try, but I am usually confused by these help articles.

For the past few months every restart of Firefox disables LastPass. I did NOT have this problem previously. The version of LastPass is current (no updates found). I can go to Add-ons and the toggle is set to "on" but the icon in the menu bar is black. If I click the toggle off, then back on, LastPass comes on just fine. Why is Firefox disabling something that Add-ons says is loaded? VERY strange. Does NOT happen in Chrome. Thanks for any assistance. PITB!!!

I have the option set to always ask me if I want to open a pdf with browser, acrobat, or to download. I usually select open with Acrobat and, for the last few months, I have been getting an unwanted download as well. I found in the help articles that this is now the default action. For me, it usually means that at the end of a session i have to go to my desktop (my optioned destination for downloads) and clean it up by deleting every file I have looked at.

I recommend that you make that functionality optional. I just want to view the vast majority of things I open. For the few that I might want to download after viewing them, i would prefer to take a proactive step to download them after I have reviewed them.

Firefox stopped opening links in web pages like secondlife:///app/region/Kings%20Stone/224/155/22 ,WHere do I tell Firefox what application to use to handle that kind of a link?

All my menu texts are so TINY now, that I can't read them, but the browser page is SO WIDE that I can't ever see a whole page and I have to scroll from side to side to read things, which is a ROYAL PAIN as I miss seeing a lot of things. No one can seem to help. I tried the limited percentage things, 67% used to work but now that is too big and when I go smaller I can't read ANY of the text, it is TOO TINY! I can't do my work! The screen shot won't paste on here.

Hello dear volunteers (followers),

After Firefox Update to 100.0, the Theme that I created (JOHN - Light Grey) stopped working properly. More Specific all drop-down and pull-down menus have been transformed to a "white" background color, overcoming the initial created one, which was "dark gray".

So I tried to revise (update) my "Theme". But this became impossible.

In Developer Hub, in Theme Generator there was a (pink) frame warning "the following manifest properties that your most recent version upload used in it's manifest are unsupported in this wizard and will be ignored: properties popup popup_text tab_loading So I couldn't edit the theme and even more I can't finish and save any changes. Well, Is there any skilled user to give me a hand ? I would appreciate too much any piece of advice ...

Herewith I attache relevant screenshots.

Thank you in advanced
