Diễn đàn hỗ trợ Firefox

I had this problem yesterday when I started up this browser it said, "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem.". So I read through the article and it said to restart my mac, so I did just that and pow, my bookmarks and history returned! Little did I know that the next day, (today) I'd start up Firefox and the message was there again, but this time, it got even worse.

       First I tried to tackle the bookmark problem, "Quit Firefox" they said, "Restart your computer." they said, "Create a new database". None of those worked, so I scrambled the internet looking for answers, all of them resolved their problems, every one else was A-ok, excluding me, and just like that, my add-ons weren't working anymore! Ad-block Plus, Dark Reader, Privacy Badger, nothing. I tried to delete Adblock first and reinstall it, because that's what their page told me to do, and I keep getting this message trying to reinstall it saying, "Installation aborted because the add-on appears to be corrupt." 
       And little did I know that every other extension said the exact same thing. So i knew something was going on that was out of my control. And then finally, the "pièce de résistance" to my pain and suffering through out this whole hour or so, pages won't even load even though I'm connected to the internet, how perfect... Even trying to update the browser won't work, downloading a new one also goes through the same "pages not loading problem. 
        So in conclusion, hopefully, just hopefully, you guys can help me out. I'll probably have to resort to my old laptop, (which is slow and almost unusable with how buggy that thing is.) seeing how my mac has also been running into problems these last few days as well before this conundrum. 

Good Luck and Happy Thanksgiving!

I have used sync for long on several devices and different operating systems (Win 7, Win 10, IOS) in parallel. Most interesting and useful is for me synchronisation of the toolbars with Bookmarks. It worked fine up to today. Today I opened Firefox and found my bookmarks as they were about two years ago. Oops... so I tried to synchronize but failed. No changes were applied to my bookmarks. I assume, my bookmarks are also being stored on several other devices I used for Firefox. However the newest sinchronization on the mozilla server does not contain the accurate valuable data. How can I manage to save sync data from a destinct device to the sync server and determine that as the current data set to be valid for synchronization with all my other devices? In other words: set the direction for synchronization. I did not find this option on my current (82.0.3 (64-Bit)) installation. Could anybody help me? Thanks Juergen

Multi-Account Containers have a drop-down control to give access to things like container preferences for a site. With Firefox 83 (basic and developer editions) this drop down is hidden behind the main browser window. You can just make out the top of the control - but the bulk of the control is being placed behind the main browser content.

Using macos 10.14.6 and Firefox 83. Latest edition of Multi-Account Container add-on.

Is there a way fix this?

• After I updated to Firefox 83, my bookmark and history shortcuts now up inside the URL bar instead of next to it (Picture 1) (I know this is part of the new update 83, how can I change this back?)

• Additional settings for the URL bar show up (as they should) after I go to a new website. Usually these options are always there (Picture 2) However, all these options disappear (Picture 3) as soon as I type anything in the URL bar and these settings won't return until I open a new tab and go to a website.

• Lastly, when switching between search engines I know have to click the search engine and then also click enter to complete the switch. (I know this can be 'solved' shift+clicking, but I would prefer for it not to take an extra action and revert back the old pre FF-83 way)

Does anyone have any how I can change it back? - Either by reverting back to FF82, or by using about:config

Installed 83.0 update for my Firefox a few days ago and noticed that fonts in browser looks worse. It bacame jagged (sharp) as if Clear Type was disabled in my system but I checked it and it is turned on. Also I don't see this problem in other browsers, Edge or IE, only in Firefox. Could it be a bug with latest update or what is it?

Greetings everyone,

I'd like to add more voices to the "listen" function in reader view.

I'm on a Win10 system and have some other (English) voices installed. However, they won't show in the pull-down menu (see screenshot).

How do I get these voices to work in reader view!

Thanks in advance!

When reloading a news website home page, Firefox returns to near the top of the page rather than at the article previously selected. This occurs only on this webpage, but does not happen when using MS Edge. On another PC, Firefox reloads normally on the same website. Both machines have the most recent Firefox updates.

Hello,

I am managing Firefox for a large organization. We are installing Firefox on 3 environments and never had any issues until version 78. I made a deployment package for version 78.0.2 ESR and pushed it to around 100 test machines. Everything works fine on VDI and desktop, but on the Surface which is the main device used by around 15000 users the browser doesn't do anything. Sometimes even the menu seems to be frozen. We use GPO to customize the browser, so no Firefox accounts, no Sync, no Pocket and other functions are disabled. Even so, as i mentioned, VDI and Desktop work normally. (also tested with 78.4.1 today, same behaviour) Another point is, version 68.6.1 ESR works fine on the same Surface device.

Any ideas?

Thanks!

Hi guys & gals, Woke up this morning to a Mozilla update (version 82) & I cannot for the life of me get any of my Bookmarks back. I have tried restoring from Show All Bookmarks, but no dates are populating. I have tried the Mozilla Profile on my PC, also with no luck. The only thing I haven't done is restored my PC to a previous time. This is very frustrating!

Any assistance would be most appreciated. Cheers Max

I have a laptop with two cameras and 3 sound inputs. On websites that use webrtc (eg. meet.google.com), a permission dialog pops up to allow or deny access to a microphone and camera.

Those permission dialogs have a drop-down, but the drop-down has only one choice. Rebooting re-organizes which camera or microphone is in the drop-down list. Probably because of USB wakeup.

So to choose which camera to use I have to reboot and hope the right one is in the drop-down.

Hey this page is talking about 64MB of memory, my God what's wrong there?!

http://kb.mozillazine.org/Browser.cache.memory.capacity

For 64GB how much to set? And how much is the maximum value?

Also, what happens to offline contents? Those cant be saved to memory! Thanks

Starting recently (maybe a few weeks ago) none of my add-ons work reliably. They all break in their own special way but considering they all broke at the same time and are all fixable in the same way I assume that the issue is with Firefox rather than the add-ons themselves.

Bitwarden doesn't work in private windows normally. A screenshot of what this looks like is attached. Currently this message is sometimes displayed when I am using a normal (not private) browsing window. This can be fixed by disabling and reenabling the add-on.

uBlock Origin sometimes stops blocking ads. This can be fixed by disabling and reenabling the add-on.

Facebook containers no longer automatically detects Facebook owned domains such as facebook.com and messenger.com so when I visit one of these sites I am not in the Facebook container and so I am not logged in. I am able to manually enter the Facebook container by right clicking on the new tab button and selecting Facebook. Then the container works and I am logged in. This can be fixed by disabling and reenabling the add-on but this deletes any custom containers that I have created so isn't even a great workaround.

As well as being able to fix these issues by disabling and reenabling the add-ons individually, I can fix the issue by restarting Firefox.

The issue always seems to occur if Firefox is open long enough but I'm not sure what triggers it.

I have other add-ons, such as Tridactyl, that don't seem to be affected. Perhaps because they don't rely on what ever it is that is causing this issue.

Hello dear Mozilla community!

I've faced an issue with search engines configuration for Firefox on macOS. I'm doing the following:

1. Removing all but one One-Click Search Engines, leaving only one engine in the list (currently my preference is DuckDuckGo): https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2020-11-17-04-32-41-395a2a.png or https://imgur.com/DKqvzZ9
2. When I type search request in the address bar I'm seeing nice and clean search suggestions from Search Provider of my choice: https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2020-11-17-04-32-13-a8d46c.png or https://imgur.com/a/slivHlF
3. Close Firefox
4. (not sure what other conditions needed)
5. Open Firefox
6. When typing search request in the address bar I see that Amazon and Ebay options are back and a suggestion line "This time, search with ..." as added by firefox: https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2020-11-17-04-32-02-4a25db.png or https://imgur.com/vjq0NCf
7. In the preference I see that those two searches (Ebay and Amazon) were automatically re-added to One-Click Search Engines: https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2020-11-17-04-32-23-91dd1d.png or https://imgur.com/ibnlzLS

That issue is happening to me across different versions of firefox and isn't new. I've been seeing it for a few month hoping that to resolve in a newer versions. But as of right now I'm on 82.0.3 (64-bit) and the issue is still there.

It's a bit annoying as I have to my preferences literally every time I need to restart Firefox (which is especially annoying to do right after restarting FF to switch to a newer version).

Any suggestions and help is welcome!

Best regards, Serhii.

Every time I need to share my entire screen on Google Meet (or any other similar app) I'm always asked if I want to share a single window or full screen. But if I try to remember the decision to always share my full screen, Firefox tells me "Firefox can not allow permanent access to your screen". Is there a way to let Firefox allow me to remember the decision forever? Thanks

Hello Please kindly advise what these properties do in about:config:

browser.newtabpage.storageVersion (and 0 is valid?) extensions.pendingOperations extensions.ui.dictionary.hidden

As the title says, a couple of days ago I noticed that all progress bars in YouTube thumbnails have disappeared. The "Watched" text is also gone. I tried clean reinstall, removing all add-ons, but it did not help. Just to check, I installed Chrome - everything visible (see image - FF left, Chrome right), which would suggest that something is up with Firefox. I also check the history settings on YouTube, everything is turned on, and I see viewing progress in thumbnails when I'm on the history settings page, but not on "normal" YouTube.

I would appreciate any sort of help or advice. My life doe snot depend on this feature, but I really like it and it helps navigate YouTube more efficiently.

For the past couple of month Firefox lags at startup. It takes the program around 15 seconds from the moment I click the icon until it's ready to do anything (with a blank window as seen in the screenshot). I've tried refreshing Firefox but it didn't help. When I tried opening it safe mode it still takes more or less the same time to start (except without the blank window). After that I tried deleting my add-ons (which aren't many, adblock and fb container) but it have any effect. I'm running it on a laptop with I7-8750H processor and 16 gigs of ram so resources shouldn't be a problem (cpu at no more than 50% at program startup). Please advise.

I managed to compile firefox on linux ubuntu but did not generate the executables for windows.

Then I started configuring on windows, but I believe the problem is with the Visual Studio version, I installed the latest version of VS 2019, then I found that it doesn't work, because VS 2019 now requires the "C" compiler version 10, and mozbuild uses version 9.

I ended up discovering in other documentation that I have to use visual studio 2017, but I installed VS 2017 version 15.9.29, however it gives error in the compilation.

I found in other documentation that I must use VS 2017 version 15.8, but this version is not available for download.

Can anyone help me what I have to do to be able to compile it?

Hello, As the headline states, I can't seem to drag and drop from Tumblr's dashboard. However I can if:

• I right click and click save image as...
• I click through to the user's tumblr page
• If I am not logged into tumblr

This has happened on a handful of other sites but I it mostly happens on Tumblr.

I restarted my pc last night, and when I opened today I was met with the following issue. Whenever I maximize a window on my primary monitor (3-monitor display), it goes full-screen but only shows a portion of the content. It brings with it a huge white border (pictured in screenshot) that registers as a portion of the desktop (or perhaps just not as a portion of the window). By that I mean that when I click in it, it is as though I am clicking out of the window and onto whatever app or object is operating behind the Firefox window.

Changing the zoom does nothing. It just adjusts the size of the display within that same limited portion. Strangely, when I drag the window onto the second or third monitors, it will maximize without issue. Returning the window to the primary monitor, however, recreates the issue. When in this mode, I cannot access the menu nor tool bars. My only way to manipulate the window is to right click in my taskbar, "restore" to a non-maximized state and work from there. When not maximized everything functions normally.

I disabled all add-ons and plugins, but the issue persists. I have no fullscreen background applications which should be affecting the application or its resolution. When I launch, in safe mode, it is better. I can maximize. The border is still present, but I am able to access the menu functions with the alt key. My software version is current. The drivers for my GPU are current.

Again, this issue happened overnight with no changes on my part whatsoever. I shut my pc down after a day of work. I booted up today to resume work, but I am unable to do so until I can solve this issue. Any advice is greatly appreciated.
