Every time I restart firefox, my spellchecker languages disappear, leaving me only with one - the addons are still installed, they're just not available to be selected. Even now I can't spellcheck in english. Please help.

When I open github it loads incorrectly as shown in the picture, after I press F5 to reload the site load fine. I have tried deleting cookies and I am using any ad-blocker. Any help? Thanks.

I have Yahoo.com on my desktop which takes me to my email account. I would like to get it on my task bar but when I try and move it down it is adding it to Firefox on the task bar. I can't seem to get it down there to stay

After installing Thunderbird i had first download problems for new Firefox Versions. I tested around, installed everything new and found the solution. Somehow the Maintenance Service didn`t work properly on my machine and after deinstalling and restarting i can update firefox again. Problem remains: When trying to install Offline Languages , see picture, i get the message that it does not work. I tried everything possible, including reinstalling and deleting all old profiles (was a lot of work). Any ideas?

I have used Firefox as my browser for many years and lately my emails won't open or if they do it is very slow sometimes and won't allow me to delete emails. Not sure why this is happening and I asked by email provider and they told me to follow some instructions about fining the menu button of Firefox which I couldn't find then he gave me a link and I tried to follow but was unable to make any progress. I use spectrum email services

I have windows 11 and the firefox 124.0.2 browser. I cannot update to the latest version of Firefox. I receive an error message "failed to update". I've uninstalled and reinstalled the browser, ran the install utility selecting update, nothing seems to work. Please help

My Firefox recently updated to version 124.0.2. Afterwards my taskbar shortcut broke, so I pinned a new one manually (right-clicked Firefox in start menu > open file location.) When I opened Firefox it had reset the primary profile to be default, so I changed it back to my BetterFox profile. Since then I've run into several oddities, such as Firefox crashing when it's running in the background, getting an error saying "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window," when I try to open it, invisible shortcuts in my taskbar(see image) and my bookmark visibility resetting from always to only in new tab every time I start up Firefox. Please help me.

I used Malwarebyte scan to check for my digital footprint and it showed Firefox , spotify and another program , it also identified one password that was out there ! Does this mean that Firefox on my PC/Phone is insecure ? or are they trying to get me to use their software ?

Hi, Following https://support.mozilla.org/en-US/questions/1199797 where I can't reply.

The provided solution isn't enough (in my case, the certificate was already there, although there were intermediate certificates without websites allowed - I added that trust, as well as imported more corporate root certificates but I'm not sure any of this was necessary).

Anyway, many web pages didn't work, as all http requests beyond the original one were redirected through zscaler proxy 2-factor auth. All js, css, images came back with a 307 and the corporate authentication page, immediately followed by a call to the redirection, coming back as 200 ... but with the same auth page. I saw that the original request (the base html) was always sent with "ssm_au_c" cookie but page resource requests were not.

I did solve the issue. I had to change the tracking protection options from "Standard" to "Custom" and uncheck "Cookies". Now everything works.

I don't really need an answer but, as others may have the issue and I can't post in the original thread (which is archived), I figured that I should post it somewhere. However, if there is a way to keep tracking protection in place and only add an exception for ZScaler, that'd be great. Adding "zscalerthree.net" in the exceptions didn't do the trick.

Hi all!

I am using Firefox Multi-Account containers with Firefox 120.0.1 (64-bit) and the New Outlook desktop client with Windows 10(*). I have more than one Office 365/Outlook account, so I use different containers for each account.

Whenever I click on any link in New Outlook, it opens in one of my Firefox containers rather than in a default No Container tab.

Unfortunately, it opens in a container where I am logged into a different Office365 account than the one I use for the desktop client. This means any Office or organisation-specific links fail to work unless I copy and paste the link across.

Is there some way to force Outlook to open these tabs as No Container?

Thanks, penguinoid

(*) I'm using a university owned/managed computer and they've disabled the option to update to Windows 11

FF has been the browser of choice for me for years. Word Press has been the weblog platform of choice for almost as long. Recently, however, FF won't accept embedded links in new posts.

If I try to create an embedded link, the link text box flickers and won't allow the text for the link to be inserted.

At the suggestion of WP, I cleared the FF cache - to no effect.

I decided to try posting through another browser, Chrome. It worked fine.

Chrome could be a workaround for this, but I'd much prefer to use FF.

Any ideas?

Thanks,

DMS

PS I use Windows 11, latest upgrade, and the latest version of FF

Hi, I can't read some DRM protected media anymore (Prime video, Spotify) in Firefox in Windows10.

The error I get say that firefox doesn't have Widevine installed (but it does).

I can read the content with other browsers (Brave) so the problem is not Windows Media Foundation i guess?

What I already tried:

-untoggling/toggling Widevine in plugins

-reinstalling firefox and using a new profile

-using Firefox Nightly

-removing the drm folder from the profile and relaunching firefox

Output of the console:

Any ideas?

When I go to sites like google or bing, ect... I used to be able type multiple spaces between words now it only lets me type 1 space between words. Multiple spaces makes it easier to cut and paste when I'm doing multiple searches
