Diễn đàn hỗ trợ Firefox

Chrome has stopped working. I cannot tell if it is Chrome, Ubuntu MATE 22.04, or a virus. I want to switch to Firefox, but cannot import my Chrome bookmarks. I tried using Chrome to export my bookmarks and then using Firefox to import them. Did not work. I tried using Firefox to import from other browsers. It could not find Chrome.

i've tried toggling media.hardwaremediakeys off and pressing the media keys to no avail, they don't seem to have any effect when it's enabled or disabled. the keys work on other applications like VLC media player, though! and I can see that the media is being detected from firefox, too, as it appears in media player widgets i have on my plasma desktop. it seems to be only the physical keys that aren't working, because i can press buttons on the widgets to control media playing in firefox.

When using Firefox browsing, every so often, on the left hand margin of the active window, a half of a black dot protrudes, about half way down the window, and then pulls back to disappear. The whole episode lasts about a second.

Certainly not a big deal. I am just curious as to why that happens. I have also noticed it on the right hand side. I don't know, either, if they happen at the same time.

Thank you for your help.

Hello,

after porting my SSD Arch installation from my old Laptop to a desktop PC, i have a really long startup time (about 30s-45s) for the first time after booting my PC. This problem doesn't occur with any other programs. The subsequent openings of firefox happen instant.

Have tried using "refresh" functionality to clean up firefox so my about:config is as clean as it gets, didn't help. Have tried starting it with "firefox --no-remote", didn't help. Have tried starting it with "firefox --safe-mode", didn't help. Have tried starting it with a completely fresh profile, didn't help. Tried purging it from the system and reinstalling it, didn't help. Same problem when I start it normally via dmenu/rofi.

I don't get any stdout log on any of these methods of starting.

I also don't know where to look for helpful log files.

Any help or hints on where to trace this fault are much appreciated.

Have a nice day :)

I am running Windows 7 (and will not downgrade to one of the newer versions). Firefox has stopped supporting Windows 7 with version 115, which I am currently running. However, I get a pop-up message each time I launch Firefox asking if I want to download the latest version (which cannot be installed).

Is there some way to stop this annoying message from appearing?

Call me old-fashioned, but I miss Netscape...

Hey there, I was using one of my macs today and it suddenly started updating. It was taking ages and seemingly stalled, so I closed the app.

Now, all our bookmarks and history is gone. Also, the now updated version is not showing my new history etc.

Is there any way to retrieve our original bookmarks, history and passwords?

Regards Peter

I've seen in many places that cmd+` should allow me to switch between windows within an app on Mac. For me, it only works in Safari and other native Mac apps. It does not work in Firefox. I have the latest Mac OS and the latest version of Firefox. Is there a solution to this? I would LOVE for this shortcut to work, since I'm also a Windows user and it's the closest thing to the Windows window-switching shortcut.

It seems Firefox is getting worse and worse. I am now back to pages loading very slowly. My IT guys say firefox is [redacted] and go to chrome or something else but i hate transferring bookmarks. WHY can't you stabilize your [redacted] browser. Yours is the only browser my PC runs into trouble with. Makes me [redacted] furious.

I've been having a weird issue with my text glitching only in my Firefox browser. Initially I thought it might be my monitor but then I realized the issue only presents itself in my Firefox browser. Literally no other program is affected.

I've done a reset, I've uninstalled and done a clean install, I've deleted all Firefox files and re-downloaded the browser. The issue immediately pops up again.

Hello Firefox,

When loading a page I work on, I sometimes see something like this:

14:54:44.103 Error in parsing value for ‘margin’. Declaration dropped. instantiate_obj.php (With a yellow-ish triangle with an exclamationmark in front of it)

The warning is clear: somewhere in the html/css a faulty margin-value is used.

But how to find out where, or what causes it?

Is it something inline, an external CSS, something dynamically added by javascript?

What I tried:

1)  Clicking on the link on "instantiate_obj.php" just opens a tab in "view-source:" mode.

Not very useful. I don't see any problems on quick inspection, but the page is pretty big. I want something easier than checking everything in the source and the linked CSS.

2) Looking at the timestamp (14:54:44.103) I see it ends in 103. Maybe a linenumber?

Nope, that particular line contains only
.

3) Searching https://developer.mozilla.org didn't shed any light on how to approach this problem.

I can only find out references on how to do it when you see the yellow-ish triangle in inspector, in the second pane (css with that 'filter styles' on top) I already checked my external stylesheet and it came out fine.

Does anybody know how to find out what caused the warning?

===========================

I asked also on stackoverflow but didn't get a response, so for reference:

Thanks for your time!

I get this error when trying to access my email using FireFox. Lately this (or a similar) error happens weekly if not every couple of days. Always first thing in the morning, too.

my email works just fine using Safari so I am at a loss.

I have tried running FF (Firefox) in safe mode, ensuring outlook.live.com is an exception to the pop up window blocker, changed default protections on outlook dot com to none from standard.... Turned off ABP, clearing cache and cookies from within FF.

it may be worth mentioning that I can still browse/access other websites while outlook produces this error, and my network settings within FF are set to use default system settings (no proxy).

Yahoo websites blocked from within the US. I get the following message: "When trying to access my yahoo mail account from within the US I get the following message: Yahoo’s suite of services will no longer be accessible from mainland China." Any thoughts on what is happening and how to correct it? I'm in the US using the Mozilla VPN with a US server location

I tried to log in to a website that requires access to my location. I'm using Firefox 114.02 on an iMac running Monterey 12.6.7. I was able to get in to Firefox's Location settings and now have the website listed with "Allow" noted. This was not enough, and for some time I didn't understand why. Then I discovered the Mac's System Preferences' Security and Privacy section, where Location Services are one category under Privacy. Selecting Location Services brings up a list of apps that are allowed to provide location information. For some reason, other browsers are on the list and can be turned on or off, but Firefox is not on the list of apps that can be selected as permitted. Am I missing something here? I can't find any way to add apps to the list so that they can actually be selected. Any advice?

Hello all! Thank you for reading this. I will attempt to be concise. All download attempts from firefox fail regardless of file type. I have done all of theses; https://www.guidingtech.com/fix-mozilla-firefox-downloads-failing-on-windows/ and I have done all of these; https://support.mozilla.org/en-US/kb/cant-download-or-save-files

The facts Dell 7490 Laptop. Windows 10 Pro 64 bit, version 22H2, OS build 19045.3086, Windows Feature Experience Pack 1000.19041.1000.0

Firefox version 114.0.2 64bit

Possible relevant information. I also encounter an error when starting Firefox that I cannot resolve. XUL Runtime error. I have attempted all the fixes here; https://support.mozilla.org/en-US/questions/1398228

Any help would be greatly appreciated. I love supporting Firefox but I"m not sure how much longer I can use it with this problem.

Thank you, Everyone!

Within the last hour or so, I needed to close Firefox while installing an app (the setup was recommending to close all Windows programs).

Had 8 windows open.

Right-clicked on the Taskbar Firefox icon, then selected the option "close all windows" - it proceeds to close each window consecutively, asking me each time for manual confirmation whether to close this window with x tabs in it - and I just confirm each time.

So then after that setup is completed, I open Firefox again - the last closed window is restored (as per the settings);

then I click on History, "recently closed windows", and.... there's only 2 windows on that list. I restore those 2, and then the list is empty - nothing more to restore.

So if I had restarted the PC, it would've just restored the 8 windows upon reopening Firefox, as usual - but since I opted to just close Firefox like this, "close all windows", I just lost 5 windows.

So could anything be done here?

Something in the files? Maybe the C:\Users[user]\AppData\Roaming\Mozilla\Firefox\Profiles\4qu1kfr9.default-release\sessionstore-backups path? There's a file called "previous.jsonlz4" in there, something I could do with that one?

Or something else?

Any help would be appreciated!

I have lots of bookmarks, which I organise into folders and subfolders. In the last month or so, Firefox will no longer save them to the folder I specify from the pull-down menu when saving but just adds them to the general bookmarks menu. To sort my bookmarks, I have to go into Manage Bookmarks and move them manually. What's happened?
