Firefox Support Forum

I was running 8 Windows with about 12 tabs per Window. AND I had it set to Continue Where You Left Off, so that each time I closed and launched FireFox, ALL Windows with ALL Tabs would open. No problem. Easy.

This morning, Firefox crashed and LOST EVERYTHING. Why did it happen? And how do I get them back?

I have noticed lately that when I have the Malwarebytes browser extension activated in Firefox, browsing is slowed down, and in some cases a site asks to reload. For example, Twitter/X takes about 10 seconds to finally load new posts, after which the site works normally. I have determined that Mbytes is the cause of the problem by running Firefox in troubleshooting mode. When I turn the Mbytes off in extensions, the problem goes away.

However, if I turn Mbytes off for a particular site by disabling current site protection, AdTrackers, Malware, and Scams, the site still loads slowly. Again, turning MBytes off in extensions, does allow the site to load quickly. The problem I'm having does not occur when using MBytes in Edge or Chrome.

I have tried all the suggestions like clearing cache and cookies to no avail. I don't know if the problem is with MBytes or with Mozilla Firefox. I've tried turning off all sorts of features in MBytes with no results. I have Firefox version 122.0.1 (64bit). My wife's computer using the 32 bit version of Firefox, and she has no problem with Mbytes.

When in fullscreen, if I move the mouse to the top-left corner and right click, a browser context menu appears. The page I'm on is using mouse right clicks, so this browser function is breaking the controls of the page if I ever accidentally click the top left corner (which I do often).

Is there any way to disable this menu appearing? I would never use this menu to minimise/close the program so I just want it gone. It's breaking fullscreen controls in it's current form

There is a bar that says: You must log in to this network before you can access the internet" and a button that says Open network login page" and then the following shows up:

The page isn’t redirecting properly

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

   This problem can sometimes be caused by disabling or refusing to accept cookies.

Please advise what Is going on.

When I click on a pdf file, Firefox opens and displays the file, rather than handing it off to Acrobat, which is my preference. I'm running Firefox 122.0.1 and Windows 11 Firefox seems to ignore the settings in General, Applications. (See attached image)

    If I set to Always Ask, Firefox displays the file without asking.
    If I set to Save File, Firefox does not save the file.  It displays pdf instead.
    If I set to Windows Default Application, Firefox displays the file.  
         (Note: Acrobat is set in Windows as my default app for pdfs.  If I find a pdf with Windows Explorer and open it there, Acrobat is launched and it displays the file.  IOW I've confirmed that Acrobat is set as my default app for pdfs)
    If I set to Acrobat, Firefox displays the file.

I see nothing in Firefox Settings showing an Add-in for pdfs Any ideas?

"Verification of this link failed due to an error" when selecting a hyperlink. I then select "Skip verification" and the link is made.

This happens on all hyperlinks. Has been happening for at least 6 months.

How can I fix or prevent this message? Thank you.

(This has happened more than once!) When Windows did a 'forced' software upgrade on my desktop PC, 3 days ago, my g-mail/email link will not load, therefore I am unable to access my emails. If I close Firefox and open the Chrome browser, I get access to my g-mail. I have tried clearing cache and cookies but my g-mail still will not open using Firefox. Do I have to ditch my Firefox and start using Chrome as my default browser just so I can get my email? Do you have any suggestions? FYI, I am not a 'computer tech'. I am retired. Hopefully your suggestion/recommendation will not be too complex for the typical/basic PC user.

Hi, I am trying to install an add-on for MetaCert. I receive the following from Firefox: "Check This by MetaCert by MetaCert". This does not help to install the add-on. This is not a problem on my other PC. Look forward to your help/suggestions. Best, Stephen Rodgers

I have no idea how I got into incognito mode and I have not found a solution on getting back out. My main problem is that I am locked into an incognito mode keyboard which I find close to unreadable.

hi

For several days now I have been receiving the message "Automatic activation of filters". It goes away after a few seconds but is extremely irritating, how to turn it off?

How do I add a link to the start page that shows when you open a new tab? I've read support docs and I don't have a "pin icon" on my toolbar... I'm on MacOS (M1) and latest (Feb '24) FireFox...... how can it be so non-intuitive? I can't find an option anywhere...

i troubleshooted everything , I did a refresh , things got worse Amazon just isnt loading Other quirks after the refresh like opening a window instead of a tab ( yes my settings show tab) It causes other websites to run slow i turned off my ghostery , ran in trouble shoot mode, amazon works fine in chrome ( which i downloaded just to check , please don't make me go to chrome )

I've been with firefox since netscape 1

We have 5 devices and have always been able to log in to any or all of them. Now, we can only log in from our laptop. I have entered the login data manually and with Norton 365. The only device we can get logged in on is the laptop. All of the devices are running the latest version of Firefox. I have cleared the cache re-booted all of them with no change.

Hello, In old versions of Firefox picture-in-picture mode was "always on top" by default, now "always on top" mus to be enabled every time I pop-out every video. Is there any solution to make picture-in-picture mode "always on top" by default?

Before, when I started to write an address, firefox did not remember and I have to write it. That was fine. Now, it remembers everything and everything is kept in the history despite I close the private and open it again. Any other person can open the private again and see the last thing you were doing. No real private browsing, no fun

I just want to express my frustration.

Today during removal of Firefox (due to bug in Windows "winget" upgrader I got two versions of FF - 122.0 and 122.0.1 so wanted to remove one) I accidentally clicked "Refresh Firefox instead" without knowing what's going to happen in a few seconds.

Soon I was presented with a nice and clean Firefox window with no open tabs, no history and no addons.

I quickly went to my profile folder (%APPDATA%\Mozilla\Firefox\Profiles) only to discover that no full backup was made prior to "refreshing". There were some files preserved - places.sqlite, cookies.sqlite, but no addons, and no sessionstore.jsonlz4. From what I can see, some of the carefully tweaked settings in about:config are also lost.

Fortunately I made my own backup on 10th of October 2023, so I recovered most addons and some of the open tabs. I'm now in the process of restoring other tabs from history. But I like to have them open for weeks or even months, so it's going to take me a lot of time.

The Refresh Firefox thing should be removed because it only destroys data. OR MAKE THE DAMN FULL BACKUP OF THE ENTIRE ***UNTOUCHED*** USER PROFILE ***BEFORE*** REFRESHING IT!!!!!!!!!

You never cease to disappoint, Firefox. Now I'll waste a lot of time to restore what I had before clicking that damn button. And I need to set up a regular profile backup because I cannot trust the software I tried to trust the most... No wonder you're losing users. That is totally unacceptable.

Any clues on how to restore my profile to the state before the "refresh" disaster?
