Diễn đàn hỗ trợ Firefox

This topic was already dealt with at https://www.google.com/url?sa=t&source=web&rct=j&opi=89978449&url=https://support.mozilla.org/si/questions/1491724&ved=2ahUKEwjh3JWX1KSRAxWDyMkDHYXfDf0QFnoECBsQAQ&usg=AOvVaw2Zp2I2jgPnZ9gkSf5UgMGS. The solution given there was to change extensions.screenshots.disabled in about:config.

Unfortunately, my Mozilla Firefox (ver. 144.0 (64-bit)) doesn't have extensions.screenshots.disabled. So what now?

This afternoon, I clicked on a link from an email and for the first time got a choose a profile pop-up. I do not want this; I have read info on Mozilla and elsewhere about its purpose but it doesn't say how to just stop the pop-up - there should be an option just stop the pop-up because I don;t want to have to choose amongst options. I have started copy-pasting the links in emails and going to Chrome and will seriously have to reconsider using Firefox of this continues. I don't want to have to type about:config or anything - this should have been an opt out or opt in thing and I want out. Thank you for your help.

Since the 145.0.2 update web pages are loading very sloooooooow. Also, images are loading very slowly, if they load at all. At the start pages would not load at all then about a week they started loading but very slow as mentioned. Any ideas/help will be very much appreciated. I am using Windows 11.

We have a URL that is linked from various sites within our institution. For two of the sites that link this URL, it works fine in all browsers. One uses 'http' in their url and the other uses 'https' in their url. Our web server automatically updates to https either way. For two other sites that link this url it works fine everywhere but Firefox. In Firefox it gives 'The page isn't redirecting properly' error. If you click in the URL and then refresh, the site will reload properly. It's only when accessed via the link on the outside pages. This is happening to anyone that tries to access it, so individual browser/cookie settings don't seem to be the culprit. I've cleared the cache, checked my privacy setting, and tried other options I've been able to find online. Any ideas??

I have private browsing disabled on Firefox but there is a way to still use it via Ctrl +H , right click an item and there is dropdown of "open in private window" and it works. However I have no other way to open private windows since I blocked it. Also when I Ctrl+T in the private browser, it says this is disabled.

Therefore this option in Ctrl+H right click menu should not be there and I don't recall seeing it before. Maybe a bug with a recent Firefox update.

Does anyone know what has happened or how to remove this option?

Thank you!

when i sign on to my computer, frequently a prompt will appear that says i have to close the old firefox. sometimes i have to close it 5 or more times before i finally get connected to the internet. what can i do? im 83 and not tech savvy. also, when i sign on-the site crashes a lot and i should restart firefox and send a report in.

I don't remember when it started but text that wasn't underlined before such as: Names of shortcuts in new tab view Titles of YouTube videos on home page, and recommended while watching a video (not on the video itself) Reddit titles and usernames (old UI)

I have checked settings as best as I can and tried disabling all extensions but still have the issue.

I recently started to get a"The security sandbox is disable" warning. I have already gone into about:config

my settings:

Content Process Sandbox Level 8 Effective Content Process Sandbox Level 0 (note in about:config this setting is 6?) Win32k Lockdown State for Content Process Win32k Lockdown enabled -- default value is true GPU Process Sandbox Level 1

I am on a Windows 11 machine. Lastpass extension for the Firefox browser does not maintain my vault data. I have to refresh each time I go into the browser. This just started a couple of days ago. Perhaps after installing a new Tmobile gateway? Ideas on how to address/fix?
