Firefox Support Forum

Hi is there a way of having the same functionality as Opera has on highlight duplicate tabs on hover. https://blogs.opera.com/desktop/2020/02/r2020-opera67-tidy-your-browsing/ I use this all the time in Opera and I would love to see this feature in Firefox.

I am trying to access my organizations Sharepiunt website (part of Office 365) from Firefox 87 on Linux.

I get the site not found screen, saying "Hmm. We’re having trouble finding that site. We can’t connect to the server at XXX732.sharepoint.com." where XXX is the organization I work for.

The hostname XXX732.sharepoint.com does not resolve using nslookup, but other webbrowsers do manage to access it.

Any suggestions?

TIA, Folkert

I have been experiencing this weird problem since I updated my Mac from Catalina to Big Sur. On full screen mode, the menu bar is normally hidden and whenever I hover the mouse pointer at the top, the menu bar automatically becomes visible. Sometimes, without any pattern, the menu bar stays there even I hover the mouse pointer the bottom or somewhere. To solve this, I always need to quit and full screen mode. As far as I know, this happens only in Firefox. Is there anyone having such an issue (and a solution for this)?

I have the same problem. It's really very annoying. Any suggestions?

After installing Firefox Version 87.0 today, I haven't been able to open the application. Each time I try I get the following error message, "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item." I have tried both running the installer again to fix it and downloading a new copy of the installer and running it, neither of which solved the issue.

I found a previous thread from 2018 detailing the same issue (wherein the chosen solution was to make sure that your firewall wasn't blocking firefox's access to the internet) however;

A) I can't even start the firefox application, let alone see if it can access the internet. B) I tried making my antivirus application ignore it (Malwarebytes), but when I tried to do so it said I didn't have permissions to access the file.

To be clear mine is the ONLY account on the computer, and is the admin account as a result. My pc is running on Windows 7 64 bit in case that is relevant (though I didn't see anything in the update notes to suggest that they're ending support for Windows 7 just yet).

Hello, How do I permit Calibre to use IndexedDB storage in Firefox? I am running Firefox 87.0 on Windows 10. Both are fully updated as of the time of this writing (26 March 2021). In Calibre 5.13.0, I enable "Sharing over the net," then I "Start server," and then I "Test server." Calibre opens a tab in Firefox but returns the following error message: "Error: Could not initialize database You must allow calibre to use IndexedDB storage in your browser to read books" I cannot figure out how to enable IndexedDB storage for Firefox. Thank you in advance for your help, Eric

Firefox alias icon keeps replicating itself in the toolbar at the bottom of screen where all of the alias icons are located. Had a session with an Apple rep which did not work. Used a virus protection app that did not remove the aliases. Any ideas?

HI I am a trainer and web developper and in all trainings and as a designer I am using the Firefox Inspector. This morning, suddenly the menu under EXTRAS is not showing anymore the "INSPECTOR". Don't know what has changed! I installed Firefox again, no change! I know, that I can still activate the inspector via OPTION COMMAND C but this is not very intuitive for my trainings! See screenshot: What happened? Any ideas?

Thank you in advance! Mathias Will

Hello, When I paste an image by Ctrl + V in a GMail message, it is put twice (for only a few days and only with Firefox, because with Edge or Chrome, it works)

Lorsque je colle une image par Ctrl+V dans un message GMail, elle se met deux fois (depuis quelques jours seulement et seulement avec Firefox, car avec Edge ou Chrome, ça marche)

Hello All,

I have been using Firefox on my Windows 7 PC (64 bit) as the default browser instead of IE for several years. It has worked very well.

I have many utilities I have written using Microsoft Office 2003 tools. Many of these tools use the VBA FollowHyperLink method and this has worked perfectly with Firefox until the latest version -- 85.0. With version 85.0, when the code executes the FollowHyperLink with an address, Firefox starts but the "new tab" is empty and the address control has the "Search with ..." message. If Firefox is already running, the method creates a new tab (as it did with previous versions) and Firefox opens the specified address. I have reverted to IE as the default browser and it works as expected -- if IE is not running, it starts, and displays the specified address.

So it appears that Firefox 85.0 is not listening for an address while it is starting. Is there a way I can override this behavior?

Thanks, Chris

When copying pics from an online source using either the FF "Copy Image" menu choice or CTRL-C and pasting it into G-mail, two copies of the pics are displayed. Dragging and dropping images works normally

I am an app developer, not a browser guy. I have a client who would like to open web sites and auto fill any user ID and password automatically. I've got the opening working but how do I send login information to Firefox so it will fill in the appropriate boxes?

I had to clear History and Cookies on my desktop to get an online purchase done. I was able to add my passwords for every site bar one (afl.com.au). It just won't accept my password despite changing it. Works fine in Brave and Chrome. Also fine on my laptop (didn't clear anything there). Any help sincerely appreciated.

Using Firefox web browser - I do a 'COPY Image' on an image, such as a cartoon, then do a 'CTRL V' to Paste into an email under Gmail. There are now TWO copies of the original. All updates and maintenance of system software are up to date. This happens under Windows 10 laptop as well as Windows 7 desktop Not sure if this is a Firefox or Gmail problem

After FireFox update to 87 build all my saved buttons are gone. The first image how it looks now. The second is how it should be. I uninstalled FireFox, removed all cache and settings, folders from AppData, registry enties and still same. Reinstalled again and still same bug.

I had stopped using Firefox due to the lack of being able to preview pictures or attachments in gmail. I started back to using it and see it still the same thing! A panel opens up asking me either to choose how to open it or top save it. Obviously if its a .jpg I want to preview it, then decide what I want to do with it. How do I fix this so I can just preview quickly?
