I teach an online Adobe Illustrator Course. Students upload (.ai) Adobe Illustrator files. Not .svg or .pdf. But Firefox changes the (.ai) extension to (.pdf) upon downloading. This is HIGHLY irritating. Firefox, in prior versions, did not do this. In Firefox settings for Applications, there isn't a choice for .ai (Adobe Illustrator) files. I 'assume' that when AI (artificial intelligence) became available is when Firefox began automatically changing (.ai) files to (.pdf). PLEASE SOLVE this as I have to manually change the (.pdf) extension BACK to (.ai) HUNDREDS of times a day.

Whether the file is opened internally or directly downloaded to the desktop, the file name will be automatically changed to garbled text。This led to me manually correcting the file name to be correct every time I downloaded, and my installation of the "Download File Name Encoding" plugin was also ineffective.

By default ALL BOOKMARKS BACKUP saves on DESKTOP (Windows 11 pro). How can I change where the *.json file is stored (downloaded). I want D:\ZTEMP as the place to save all downloaded files as in settings "Files and Applications" "Downloads" "Save files to" D:\ZTEMP for me. example bookmarks-2026-01-03.json is placed on DESKTOP; I want in D:\ZTEMP. Thank you.

If I check "Always ask you where to save files" to true, the settings is reset to "false" after I restart my browser. Is this a bug? How can I make this setting persistent?

I use Firefox 146.0.1 (64-bit) for Windows 11

Hello! See the screenshot please: so, I downloaded à pay-bill, with Firefox (under ubuntu), in private navigation, and I get the file with a padlock-symbol at the end. What means that? What means that for me (on my computer), what means that for à friend, when I sent him the pdt-file (can he open it?). Nota: I understood that I can choose between "delete downloads when closing the privat window" or not. And I choosed not to delete them (but there appears this padlock-symbol). Thanks for your help!

in my opinion downloading files requires much time compared to other browses so i just wanted to request if you can help to improve the way of saving files.thanks bold text

O, woe, I feel like Jacob Marley wailing in torment, ha! My correctly-set selection of "Always ask you where to save files" still does not function in 146.0 on Windows 10 after I have gone through every permutation of settings, updates, restarts, etc., I can think of. Why does it always every time only automatically download to the download "Save files to" location (which one MUST set with no option to not set a download location). I have even selected "Ask whether to open or save files" on the "What should Firefox do with other files?" section. I want to be asked each time where to download just like Firefox used to allow and still falsely promises. Am I doing something wrong, or is it a vast Left Wing conspiracy with which Firefox is colluding to oppress people who want choice over their lives like me? :-)

Download not adding a number to like files when saving. For instance (mycardexp.doc if I download the same named file tomorrow mycardexp.doc it use to add a number like mycardexp(1).doc FF has stopped adding the number showing that multiple files by the same name exist and how many.

I designed a label in Avery, downloaded as a PDF and told my download to always open in Adobe Acrobat Reader. When I try to open the download I'm told that Reader can't pen because it is either not a supported file type or the file has been damaged. How can I change the program that opens my downloads? I'm using latest Firefox on a Windows computer.

After a PC reboot, when I launched firefox, all of my data was gone (extensions, bookmarks, passwords, etc) and it was as if I was launching Firefox for the first time. I wasn't sure if something happened to cause firefox to become corrupted, so I did a complete reinstall (uninstalled firefox + deleted all mozilla folders + deleted mozilla registry entries).

After reinstalling, Firefox now does not ask where to save files. Both "Always ask you where to save files" and "Ask whether to open or save files" are enabled in firefox settings. browser.download.alwaysOpenInSystemViewerContextMenuItem , browser.download.alwaysOpenPanel , and browser.download.always_ask_before_handling_new_types in about:config are all true as well.

Is there anything I can do to fix this issue and get firefox working as normal?

I have the settings set to ask where to download files I'm saving to my computer. When downloading and/or printing a document, Firefox saves a copy to my desktop even after the "save to" prompt and saving the file to a specific location. How can I stop this?

Thank you in advance!

My settings: Downloads: save files to: [custom default folder, unimportant] Always ask you where to save files: ENABLED

Applications: PDFs: Open In Firefox (because when the browser has such a nice built-in pdf viewer of course I would like to use it)

Expected behavior: Browser will open the dialog box for where to save the pdf, save the pdf, then open it in the in-browser viewer from the location it just saved to. Or possibly: save the file to TEMP and then open it in browser, I can see the argument for that behavior, though it wouldn't be my first instinct.

Actual behavior: Browser blindly saves the pdf to the specified default folder, then opens it in the in-browser viewer.

What is the actual point of the ALWAYS ask checkbox here? From what I can find extant on the forums the devs somehow don't seem to consider this a bug, so does anyone know how to wrangle the config page and/or some kind of extension into producing the actual logical behavior for these settings?

If I click "Display the progress of ongoing downloads" I can see what is currently downloading, but then when I click "Show All Downloads", nothing shows on the next screen. I've rebooted and restarted Firefox several times, on one or two occasions items DO come up on that next screen, but usually nothing is showing.

One of my jobs requires me to download work related documents on my personal pc. I would like to assign the website of the platform we use to download those files in a specific folder so i could delete them easily afterwards. Are there any plans to add such a feature to the browser? Is there a way to do it already? (without having to use the "always ask" option) Thanks in advance. Cheers from Uruguay
