I cannot removed total adblock and especially the ad for total adblock. I tried to follow the instructions, but they do not bring up the menu that they are supposed to bring up. HELP

As from v100.0, Firefox allows users to "set their preferred color schemes for websites".

Ironically, this does not addresses complaints from users, including me, who wish for a consistent Light theme all across Firefox.

Even if "Web site appearance" is set as Light, the following still remain dark:

• Background of main drop-down menu (Containing "Sync and save data", "New tab", "Print", "Settings", etc)
• Background of right-click menu (Containing the refresh icon, "Save page as", "View page source", etc)
• Background of "Please enter primary password" menu
• Background of auto-filled user name and password menus
• Background of elements in a bookmark folder
• Background of Downloads menu
• Background of Print menu
• Background of "Clear all history" menu
• Background of "Find on this page" menu
• Background of "You are about to close X tabs" warning menu
• Colour of title bar for "About Mozilla Firefox" window, when the window is not currently active

Being able to set "browser.theme.toolbar-theme" permanently as 2 would fix all of the above, but users are still (Note: Since v96.0, when this complaint was raised) prevented from doing so. Why?

Each time Firefox updates, the email client changes to the outlook default. The last 2-3 updates, mailto does not appear on the file,settings,applications menu. Nor will it populate if I type it in. I have tried every instruction to no avail. I am a long-time firefox user, non-techie and it is discouraging when things disappear with each update lately. Would appreciate any suggestions. Thanks

Before the most recent update (version 98.0), my default setting for pdf files is to open in Firefox and a pdf website I use prompted a download window when I clicked 'Download'. It has 'popupDownload=true' in the link which I believe did the trick.

After this update, clicking the same button just opens the pdf file instead of showing the download window, ignoring the command in the link.

Can anyone help me out? Thanks in advance.

Why why why why is FF forcing download of pdf files? It is a horrible problem for me.

Especially because I am a university prof and, in the classroom, constantly display (my own!) files from the course management system on the classroom devices. I DO NOT WANT MY FILES SAVED ONTO THE (PUBLIC) CLASSROOM DEVICE. Never mind multiple copies as it will download EACH AND EVERY TIME I open it.

I have been looking everywhere for a solution or a way to disable this feature, there seems to be no such option but I am seeing a lot of posts from people who object to this as much as I do.

After many many years of loyally using FF and a paid subscriber to some Mozilla services, I am afraid I am going to have to give up using FF is this isn't fixed NOW.

So this morning (5/4/2022) I start the computer (desktop) Win 10 Pro, 64 bit and Firefox will not connect.

Checks: I verified that my phone connects to my wireless; I verified that email is connecting; I verified that Chrome is connecting.

I did the following:

I refreshed Firefox -> Firefox will not connect I started Firefox in troubleshoot mode -> Firefox will not connect I uninstalled and then restarted my computer and then reinstalled -> Firefox will not connect

Further, the once working about:config update to reinstate compact menus has no effect (why not test for a mobile OS before expanding the menus...?) Regardless, this secondary for the moment.

What to next is a mystery to me. Firefox has become so troublesome that it is almost not worth it to continue fighting with it.

I updated my Firefox and it deleted all of my bookmarks I followed instructions found online, however when I click "manage bookmarks", the "import and backup" tab is not there

I use a program called Solver to generate reports and download them in the .xlsx format. After a recent update in Firefox, my downloaded files no longer contain an extension and instead only appear in my download folder as a generic "File".

I've checked and .xlsx files are definitely associated on my computer with Excel. Also when I open the file or later "Always Open Similar Files" they open using Excel no problem.

What's the reason these aren't getting an extension added to them? I've attached a picture where file 1 is what it looks like for a file downloaded using Firefox, file 2 is the same file that is opened at the time of download.

My issue kind of looks like this one and it seems the issue was a bug and the user needed to download a new release of Firefox: https://support.mozilla.org/en-US/questions/1277280

I just installed firefox on a linux machine, and spontaniously, I keep getting a message pop up toward the top of the screen saying: "To play videos, you may need to install the video codecs".

This occurs when I am not even trying to play videos. I can play youtube videos fine. I don't need to install anything. It normally occurs when I am checking my outlook email, but can happen at any time.

So my question is, how do I stop this message from coming up? Prefereably WITHOUT installing some codec that I do not currently need.

Another message that comes up is an offer to install an outlook extension to my browser, but this is triggered by opening outlook email. I have no need for this either, so it would be nice to get rid if this message popping up as well.

Thanks

I know firefox version 98.0 changed how downloads work, but I have my settings for downloads set to "Always ask you where to save files" and specifically for PDF files, I have the action set to "Always ask". However, when I click download on a PDF file and then select "open with firefox" as the action option, the file not only opens in the browser, but also gets downloaded automatically without even allowing me to select where. Is this intended behavior? There are lots of times I just want to view a file and not actually download it, and this is quite annoying.

Why is firefox automatically downloading strange files I've never seen before? (MEUIVFJ-.htm and 3tHMwYhc) They look a little untrustworthy. My download dropdown suddenly showed me that one had been downloaded, and then a while later the other one was downloaded. Are these actual Mozilla files? Or are they some kind of scam/trojan/spyware? I just realized that two were downloaded last month as well.

OS: Windows 10 Firefox Version 100.0 Starting this afternoon...

Firefox crashes (completely shuts down) every time I try to print to "Save to PDF" with the Firefox browser page open. I can print a browser page to my local printer, but not to "Save to PDF", even if it is in Troubleshoot Mode and even after Firefox has been refreshed.

Everything on my system is current and updated.

This issue is new.

Any ideas, or other suggestions.

Thank you in advance for your time and assistance on this matter.

Hello. With version 100.0 came multi-language spellchecking. I would like to know how exactly does it work, please.

For instance, if I enable both English and French, will it simply virtually add the two dictionaries and use the resulting combined list of words? Or will it try to understand if a paragraph or sentence is English and mark non-English words in that paragraph/sentence as incorrect even if they are French?

I am obviously asking this because there is no detailed information at https://support.mozilla.org/en-US/kb/how-do-i-use-firefox-spell-checker.

hi,

My firefox is downloading all the adobe files even though i have turned of the auto download option. Also whenever any pdf file i try, it gives me an option of open with or save file. I am trying open with & firefox still downloads that file to my system. Can anyone help

Hi Firefox team,

First of all thanks for this amazing product.

I hope you are aware that drag and drop to Outlook 365 (online version) on Firefox browser v99.0.1 is not possible.

Regards,

Simply put, I have used the website:

http://www.wizard101central.com/

For MANY years, and now your system wont let it load. I have spent over an hour going through the endless links in your "help" system with no help at all.

This site is not loading and the lock with the red line wont let me disable the darn thing.

If I have to choose between Firefox and being able to access what sites I want, then Firefox will lose the battle.

I have tried all your little "help" suggestions and none work. I have been a faithful Firefox customer for about 12 years, but the end of that era is quickly coming to a close.

For your sake, I hope this is something you can fix easily because that website has thousands of loyal customers that are having the same issue with you that I am now.

Hello, I just installed windows 10 on my nephews computer. I installed firefox so I don't have to use edge, but firefox won't start. It just flashes. I have tried re-installing firefox, deleted all mozilla and firefox files and folders and clean installed firefox, even reinstalled windows. Troubleshoot mode don't work, it just flashes too. I checked for Crash Reports, but there are none. The only time it works is when windows is in safe mode, I even upgraded to computer to windows 11 hoping that it would fix what ever is going on. But it didn't. I honestly have no idea what to do next. Firefox has worked on that computer before. Everything else works fine, it's just firefox that won't work. If anyone has any ideas, please let me know.

Before update when I clicked in PDF viewer toolbar download button it opened a screen to open with, right now it only download a file. I want it back. I have firefox as pdf viewer, but sometimes I need to open file with Acrobat DC, that's when I did click download button. It works on other computer like before, it is before firefox update.
