Past experience. With just a few tabs open there was a "+" button at the right hand end of the tab bar for a new tab. When the number of tabs got too many (in my case 18) the "+" button was JOINED by a ">" button to be able to see tabs off the right hand end of the toolbar, but still use the new tab button.

Post update to the current version of Firefox, at the point the ">" button appears it is REPLACING the "+" button.

I know there are workarounds, but my "rut" is to use the "+" to get a new tab.

Is there any way of getting it back?

When I'm trying to go to a specific website, it doesn't connect with an error code "SEC_ERROR_UNKNOWN_ISSUER". I was able to press a button labeled "Accept the Risk and Continue" before, but the button seems to have disappeared?

This was my fix for scrolling not working when hardware acceleration enabled. Upgraded this software product: X-Mouse Button Control (of Highresolution Enterprises) to latest release 2.20.5

I have a list of clickable bookmarks that normally displays in the left side panel. It's currently missing. If I click on 'Other bookmarks' it appears to the right but is not pinned and doesn't seem pinnable. How do I get it back to displaying in the left side panel all the time as before? Clicking on 'Bookmarks Toolbar' or 'Bookmarks Menu' doesn't bring it up. I don't see any other options in the side panel nor do I see anything relevant under 'Bookmarks' in the top ribbon menu......? Many thanks and regards Ray

for new file types the option to save the default behaviour for future downloads is no longer avaliable for me. Also, the option to set in "Settings -> General -> Files and Applications" does not show any of the new file types.

I've tried re-installing firefox, as well as refreshing but still the same results.

For a few weeks now, Firefox has been often freezing a webpage for 5-10 seconds during browsing. It mostly happens when going back to the previous page, but also when clicking a link or doing a google search. For those 10 seconds, you can't do anything on the page; no clicking other links or selecting text.

I've already tried: - troubleshoot mode; it still happens when all extensions are turned off - turning on/off hardware acceleration - creating new places databes - updating to the newest version

What can i do to fix this?

Hi. I have problem with firefox account addon. I acidenty remove it from the addon menu(that one on the right up corner in firefox) and i can't find it in addons setings. how can i add it again to addon menu?

I got a notice that Firefox (and Thunderbird) were updated this morning. Took me an HOUR to find out how to make the miniscule font in my inbox larger. So.. suddenly, new problem.

When I click the Firefox icon to launch the browser, and reopen my tabs, It opens for a millisecond, then closes faster than I can try to read if there is an error. When I click it AGAIN, all my tabs are GONE and I have to search for them manually, which is a royal pain.

Why is this happening? How can I stop it from happening? This is annoying as hell.

I use Firefox on a PC to access Facebook (website, not app). This week the Messenger/Chat feature stopped working. I click the icon and it opens but nothing appears in the box, it just hangs. There is an option to open in its own window, but that also is blank - no past messages, no contact names, no ability to start new message. When I log onto Facebook in Edge, Messenger works fine in Facebook.

I've tried everything I found on the internet for this issue - updated and refreshed Firefox, cleared history/cache/cookies/site data, uninstalled and reinstalled Messenger, refreshed Facebook to initial settings, used Firefox in troubleshooting mode, reset everything, turned off browser, turned off my computer, used shift key to reload tab - nothing has worked. There are some instructions about stuck cookies, but I didn't understand them so I didn't try that one thing. I've gone into every menu I can find to try to figure out this issue, which isn't the end of the world, but I would appreciate some other ideas for what is suddenly causing this. Because now I have to redo all of my settings and preferences and logins and the problem still isn't fixed.

I hope this applies here. I tried using the "-p" command fro Librewolf. Wiped out my sessions and settings.

Is there a way to do this in Firefox and or Librewolf?

I can sync my home desktop (Windows 10), home tablet (Windows 11), and phone (Android) just fine, but I am having trouble syncing with my work desktop (Windows 10). As I can work from home, I would like to keep my bookmarks, history, etc. synced.

While at work, when I start Firefox, it says that I am running an older version of Firefox and either need to create a new profile or exit to avoid problems. So I create a new profile, then update to 117, then restart Firefox, and things are fine for a bit. Eventually though, if I exit Firefox, it will go through this cycle again the next time I start Firefox. When I check the version after starting, it says that I am on version 115, even though I already updated to 117. I went into about:profiles I saw that there were several profiles there: default, default-release, then default-release-1, 2, etc., with the most recent number being the one currently in use.

Could this be some sort of organizational setting that is preventing the update from sticking? Is 117 not 'backwards compatible' with 115, so to speak, with regards to syncing? Any way to work around this? Any insights here would be appreciated.

Has the Autofill Forms option been removed from the latest version of Firefox? I get the opportunity to autofill credit cards but the Forms section seems to have vanished. Am I missing something? Thanks.

From a security / QOL pov I'd like to disable an extension on some websites, and was wondering if there were any methods to do this?

I searched this question first through reddit and the support site and found similar questions with no updates asked between 4-6 years ago, wondering if there's been a method implemented yet or if it's still not possible.

Thanks!

firefox is not prompting the primary password login dialog box and not even providing me "saved login"

Even when i tried to open password in settings so that i can manually copy paste them, it ask me to log in first as shown in picture but when i click on login, nothing happens, it does prompt primary password login dialog box.

as shown in picture below, even if i click login, it just does not work.

p.s tried clearing cash and cookies.

I occasionally use a site (www.zoomcare.com) which does not work properly with Firefox (I've been using Microsoft Edge (Windows 10) to access it). The problem comes when I try to login. I enter my username and password, and that brings up a blank page that does not redirect to anything, so I'm stuck.

Just out of curiousity, I was looking through Advanced Settings, and found security.csp.enableNavigateTo. It has been set to false, but when I set it to true, I am able to successfully login (I still go to the blank page, but after a brief pause, I'm redirected to a logged-in page).

I'd like to know something about the security implications of enabling this property. Is it a bad idea? (Not knowing, I've set it back to false and will continue to use Edge for now).

Chrome scrolls to element while Firefox doesn't for this URL with # :

https://www.service-public.fr/particuliers/actualites/A15610#titreChapitre_-5776306477855185115

There is an element with id "titreChapitre_-5776306477855185115" in the page (chapter "Personnes ayant un test de dépistage positif" which means "People who test positive to Covid", Chrome will scroll to this chapter (well, at least 60% of time it auto scrolls to the element) while Firefox will always display the top of the page.

Firefox is slightly better and more similar to Chrome on the english version for some reason : https://www.service-public.fr/particuliers/actualites/A15610?lang=en#titreChapitre_-5634635573997558496
