Diễn đàn hỗ trợ Firefox

I'm running mac os 10.13.6 and have installed Firefox 118.38 ERS but some websites are not allowing me to proceed due to my system being outdated/unsupported, what can I do about it? Cheers in advance for any pointers.

We recently had an update on our printer drivers and somehow this has swapped settings from the previous system print dialogue to "Firefox - Print". The Firefox print dialogue does not have print preview and I need to be able to see a print preview. I've noticed that this was an issue in the past and people have solved it by going into about:config and setting print.tab_modal.enabled to false, but this hasn't worked for me. I am asking this question because if I can't find a solution I will have to switch to Chrome so I can see a print preview and I would rather not. If there is another way to force the system print dialogue instead of Firefox, please let me know.

For some scrollables, v153 doesn't respect the Mac OS setting to hide scrollbars unless scrolling on page load. If that OS setting is adjusted after the page is loaded, then the page respects it again until refresh, so there's apparently some sort of race condition going on where it's not reading the setting in time before the page loads?

This is not a problem in v152. I downgraded back to v152 and it's working again.

Every thing will be working fine? And then I click on something, and it takes a long time. And then at the top of my prompt, it says Mozilla firefox is not responding. I've been dealing with this for some time now. You can't figure it out. This is happening on my computer. Also I would update it the program and the very next day.There's a prompt asking me to upload again. I upgrade, and then I still get the same thing.Mazilla is not responding.

Hi, On previous releases of firefox I could load 8 items across the home display. After upgrading I can only get 5 items and I can't find a way to increase this. I'm a new user so maybe I'm just dumb but I would appreciate some help. linux/ubuntu/firefox desktop. mike_a

Following is what I see on the screen:

After updating to the smart window(beta), the AI chatbot providers in sidebar cannot be found, if it is possible, please add it back, it is so useful. And the new features look pretty nice, cheers

Anyone succeed with running Firefox in headless mode under Ubuntu?

I tried:

firefox --headless --safe-mode -P headless https://quan.hoabinh.vn

but got this error:

[12545] Sandbox: CanCreateUserNamespace() unshare(CLONE_NEWPID): EPERM

• • • You are running in headless mode.

[GFX1-]: RenderCompositorSWGL failed mapping default framebuffer, no dt

I installed Firefox as from "https://packages.mozilla.org/apt" repo.

Until I close the following message that appears on Firefox Screen other apps are slow or won't open.

Box with Red X - This profile was last used with a newer version of this application. Please create a new profile. OK

I followed the directions to CREATE A NEW FIREFOX PROFILE.... ,, created as Personal #1 & Personal #2 perhaps I did something wrong......Help!!!!

Hi Team,

In Firefox, the close button is only partially clickable and is not accessible on the right side. However, when I hover over it, a square background appears around the button. Could you please take a look?

Thank you

Firefox prompted me to update, I hit download, my entire PC froze, I restarted the computer, when I opened firefox again and hit "restore session" it restored a session that I had opened months ago. When I checked my history, everything after that older session had been deleted. All of my history from the past few months has been deleted. I tried a few different solutions from trying to research the problem, nothing so far has worked. The only thing I have found is a session restore error saying "could not decompress file", but I could not find the file it was attempting to decompress. This is the error message I found.

1785894397652 SessionStore ERROR NotReadableError when reading session file: recovery: NotReadableError: Could not read `C:\Users\ansen\AppData\Roaming\Mozilla\Firefox\Profiles\xpnhovd6.default-release\sessionstore-backups\recovery.jsonlz4': could not decompress file: invalid LZ4 header: wrong magic number: `00 00 00 00 00 00 00 00 00 00 00 00' (NS_ERROR_FILE_CORRUPTED) No traceback available 1785894397756 SessionStore ERROR NotReadableError when reading session file: recoveryBackup: NotReadableError: Could not read `C:\Users\ansen\AppData\Roaming\Mozilla\Firefox\Profiles\xpnhovd6.default-release\sessionstore-backups\recovery.baklz4': could not decompress file: invalid LZ4 header: wrong magic number: `00 00 00 00 00 00 00 00 00 00 00 00' (NS_ERROR_FILE_CORRUPTED) No traceback available

Any help is greatly appreciated. I'm one of those people that tends to have way too many tabs open at once due to poor memory, and losing months of tabs and progress is a huge setback. I'm very desperate to get the history and tabs back.

It seems I can no longer set a link to open in same tab. There is a Government webskite that won't let me open a link in a new tab and I can no longer find a way to stop a link being opened in a new tab

I have used [email removed by moderator] for all my emails and have opened them on Firefox on this computer but can no longer login to see them. All emails are available on my i-phone and I use i-cloud for storage. I would greatly appreciate your help.
