After migrating my Windows Live Mail (WLM) 2012 email folders to Thunderbird, I saw that the folder names were truncated and not the same long name I had the folder named in WLM. I have been editing the folder names by copying the WLM folder name to my clipboard and then renaming that truncated folder name in Thunderbird by renaming the folder use the CTRL-V (paste from clipboard).

Prior to today after having done the above, the renamed folder in Thunderbird was moved according to its new alphabetical name in the listing, but usually in the same vicinity of folders that I was renaming. Now, the newly renamed folder seems to disappear from the listing. I scrolled through all of the folders from a to z but couldn't find it. Out of desperation, I closed Thunderbird and then reopend it to see if that would refresh my list of folders with those folders I had just renamed. And, sure enough all of those renamed folders are visible and in the correct alphatical place on the list.

Any guidance or insight would be greatly appreciated!

By using Process Explorer or Process Hacker or maybe task manager, I hope you can also verify that Firefox consumes a few GDI handles per open tab. Windows has a global limit and a per process limit of 10000. GDI objects are used for windows, for the file save dialog and also for user interface elements like buttons or lists. However many applications like Firefox draw everything themself like XUL etc. But still, Firefox consumes 3 handles for me (verified on another computer) per open tab.

If you have a lot of tabs open (for reasons not to be discussed in this topic) this can be problematic. If it reaches 10000 windows will not create more. Sometimes firefox hangs, but often Fullscreen (e.g. youtube videos) will not work and the gui will disappear. Also the context menu will not open and the save dialog cannot work and is hidden.

Am I the first to report this? I did not find anything. Can this be fixed? Can I post this to bugzilla?

Can anyone confirm this? The latest version does not fix it.

I'm no longer able to play youtube videos on Firefox. I've tried everything from re-starting laptop (this worked initially) to refreshing/ updating Firefox browser as well as clearing Firefox cache and cookies. Any help will be appreciated.

Thanks, MC chowbabyhi@aol.com

p.s. youtube does work and play on my Edge browser

When I type in the search bar, for example, 3+3 (also tried 3 + 3), when I enter, it will give me this "3 3" and will just show results instead of the calculator.

It, however, still work normally if I were to write "3 plus 3"

Firefox was working well on my desktop computer until I used Avast software to "optimize the computer. Now the only software I can bring to the screen is AOL email.

Firefox is working well on my husband's laptop. So the problem has to be solely on my desktop. And is probably due to optimizing performance. I checked Avast but the Help claims no problems occur when optimizing.

Right now, I get an error of a Tab being broken.

Right now I am using Google Chrome but I would prefer to get this Firefox problem fixed.

The Firefox app I am using is the latest version, 134.0.1

I was browsing normally when suddenly the right click menu stoped doing anything. If I right click it still opens but nothing I click on does anything. I can't copy, paste, open a link in a new tab etc. It also appears to have new options on the menu that I don't recognise. I have no extentions or pluggins exept what comes default so I doubt it's that.

I tried in another browser and it worked fine so it's just firefox.

Dear,

Since two days, my firefow desktop browser (windows 11 - surface pro) switches to tablet mode (larger address bar suggestions etc) when the computer should be in desktop mode.

Situation: - Surface tablet without type cover connected - docking sation usb -c - 2 external displays connected - bluetooth keyboard and mouse connected

Windows recognizes 'desktop mode' since all menus (taskbar e.g.) are behaving in desktop mode (not larger). However, Firefox for some reason switches to tablet mode (see image attached). When I connect the typecover keyboard, firefox switches to desktop mode.

So it seems as if FF thinks the PC should be in tablet mode because the typecover is not connected. But it shouldn't because a dock is connected.

It worked perfectly for years, but since two days not anymore. It is not a major issue, but rather inconvenient. I already restarted PC and reinstalled FF.

kind regards

I received the following error message when trying to connect with a site which I have been using for several years. The advice below the error message directs me to contact the site owner, but I can't do so if Firefox will not let me access the site. What to do?

When attempting to perform a google search, if I include the text "c++" in my search, the "++" is always chopped off. It doesn't matter where it is in the search text and also happens if it is the only thing in the search. This also happens if i choose a suggested search topic that has the ++ in the search topic. I do not experience this with Edge and i do not experience this with Firefox installed on another computer. I am signed into the same profile with both computers. I am running Windows 11.

I can repro this issue with +, #, and &. Other special characters seem fine.
