I have recently been getting an error message when I open Firefox saying "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem". This has been happening since I clicked on a mail in Mail to unsubscribe from a spam/phishing mail list, which seemed to result in me installing Firefox Private Browsing, which I had never subscribed to. I have tried uninstalling Private Browsing but there is no way of doing that. I have even uninstalled and then re-installed Firefox completely but I still have the same problem. Because of the problem I have now lost all my bookmarks and history, and am unable to create new bookmarks and history. I have been on the help forums and seen that I can Disable Private Browsing by going through my anti-virus (Avast), which I have not yet tried because what I would really like to achieve is uninstalling and not having Private Browsing on my Start menu, rather than simply disabling it. Anyway, would disabling it solve the bookmarks and history problem ? Can anyone give me the solution ? Thanks. As you may gather, I am not very techno so you would have to give me the idiot's version of any instructions or advice.

hard drive failed on windows 10 pc, new drive put in & window 10 reinstalled with Edge browser (by experts) What do i do to get firefox browser as my main browser back with all my bookmarks etc & firefox VPN ?

Do I just download firefox installer & sign on & all bookmarks etc will be there?

Thank you for your help, Tony

I believe that TBird in the past would show the count of the selected messages in the bar at the bottom. For example if I selected 10 messages in a folder for deletion it would show at the bottom how many were selected. If I selected a thousand it would show that number, and then when I hit delete it would show a progress of x number deleted of so many selected.

Now it no longer shows the number selected and during the delete process only occasionally flashes the x number deleted of the number selected.

I believe this is a bug in 115.11.1 It is occurring on two different PCs both running Win 10 Pro.

Mein Laptop reagiert nicht, wenn ich mich über lockout abmelden will. Mir wird stets die Seite "Fehler: Gesicherte Verbindung Fehlgeschlagen." und nicht wie vormals beim öffnen des Laptops. Wo liegt der Fehler?

Have been using Thunderbird for years with my cox.net account. Recently TB update115 happened and cox.net go moved to Yahoo. Under the old systems, (cox.net and pre 115) I was able to have spam emails delivered directly to my Spam folder. With the migration of cox to Yahoo, and TB 115 I don't have a Spam folder. I have a Bulk folder and a Junk folder. I have figured out that the Bulk has replaced the Spam folder. However, spam does not show up in the folder automatically. I have to select the folder, then after about 3-5 seconds messages will appear. Again, in the past spam would be moved to the spam folder and the folder would change to dark and a # would appear beside the folder indicating that a new message had been added to the folder.

Is there a way that I can set up TB115 to do the same thing? I have tried but I can't figure it out. Thanks in advance.

For the last few weeks i've noticed youtube vids buffer but then sometimes stop and when the video reaches that point on the bar it skips about 5-10 seconds, then contines to buffer like normal, so I have to use the arrow keys to go back to see what I missed. It is very annoying. Happens almost 1-2 every day at random times. My wifi speed is good. I've cleared cookies and caches, turned off enhanced tracking protection for youtube, i've even increased perfomance settings for intel graphics in my pc's power manegment plan. Nothing! Can anyone help, thanks.

When i scroll up and down on a page, it instead provides the back-page instead of scrolling up and down on the website. this is for all websites. the scroll function works oroperly in system settings, it is only with firefox. autoscrolling is enabled in settings.

There are a bunch of obsolete suggestions on opening FF without address bar, menu bar, etc., and kiosk mode.

I do not want Kiosk mode, but do need ability to open it via command line so that only the title bar (and borders around the app.

The most current available entry on the matter in the Mozilla site no longer works (at least for me) --

firefox.exe" -ssb https://www.example-site.html/

Also even if it did, not viable to update all FF users as these are customers, and they won't, simple as that. Chromium browsers just work by passing the command by default.

This is for use to launch a local help/users guide from a Windows application. Can do so on Chrome/Edge, but leaving out FF is less than ideal.

Hi Team,

Just installed latest version of Firefox - and cannot login into the browser to enable applications menu.

I can login into my Mozilla account but how do you login to this new version of the browser?

Appreciate your assistance

I work pretty much exclusively using Unified Folders, in particular a Unified Inbox. Thunderbird 115.11.0 checks for new messages on schedule and downloads from all three of my accounts automatically throughout the day. But if I want to do a manual download, the little cloud-with-an-arrow checks only my primary account, not the other two. Yet when I right-click the little cloud, that identical icon purports to represent all accounts. Am I misunderstanding something? Is there a way to essentially replace the one little cloud with the other so that a right-click and second selection is no longer necessary?

I have been given an email account as a board member of a local non-profit organization. I have tried but cannot get it to work in Thunderbird. It does, however, work on my Apple devices (iPad, iPhone & Watch). I'm missing important correspondence by not being able to get on my desktop. Any help will be greatly appreciated.

This requires some explanation.

I have 6GB of RAM, and am running Windows 7 64b.

I just updated to v115 from v56esr. I was using an extension that broke when the quantum update came out, and I wasn't willing to let go of it so I stopped updates. When the occasional website stopped working on the old version I would use Chrome for that website, but Firefox has always been my preference. Chrome was such a memory hog that I couldn't have more than a dozen tabs open at once before it crashed, and for me that is unacceptable. At this point however, enough websites have ceased to function in Firefox that it was worth it to me to update. After updating I found that Firefox uses just as much memory as Chrome. Where I previously could have 30 or 40 tabs loaded at once before running out of memory, now I only get about a dozen.

Question: In what version(s) did the memory consumption drastically change? What version can I revert to in order to bring memory consumption back to a manageable level? What other settings can I tweak to reduce memory usage? (For example, can I automatically reject loading of subframes?)

Please Note: - I use adBlock+ and I have made a habit of turning off tracking and rejecting cookies and notifications everywhere I go online to prevent excess resource usage, among other things. - I use very few extensions so there isn't really any memory to save there. - I understand that my computer is old and should be upgraded. Telling me to get a new computer or add more RAM is unhelpful and will not be appreciated. - I also understand that running out of date software is a security risk and is not recommended. I don't care, so don't bring that up. - And I also understand that I am a tab hoarder. Because of the way I work I typically have 50-100 tabs open, but I periodically close it so as to unload everything and usually don't have more than about 30 active tabs at once. - I know that some websites (particularly those with lots of subframes) use much more than other sites so my memory usage is entirely dependent on which sites I have open, and I know that I can open the task manager to close/unload unnecessary tabs and subframes. Having to do that frequently is a pain, and it doesn't work if I need all the tabs that are active.
