Diễn đàn hỗ trợ Firefox

I haven't changed anything in Firefox Browser settings. But when I open a bank statement, it is opening in the firefox browser, not in Acrobat. For years it opened in Acrobat. I checked Firefox Settings - Downloads for .pdf and it is still set to open them in Acrobat application. I have toggled the options, but still will not open in Acrobat. I have rebooted PC and tried again, still not opening the .pdf in Acrobat. Please advise what I should do Thank you

If I go to save something from within Firefox (on MacOS desktop browser), if I try to forward delete some characters, nothing happens. I can go to the address bar and forward delete characters within a URL, but doesn't appear that I can do so in other dialog boxes within Firefox. I've verified issue persists in debug mode as well as standard mode (and just re-freshed firefox within the last day and thought that had resolved the issue until realizeing forward delete will still work in URL field, but not in firefox dialog boxes like the save as window when downloading something.

Copying this from a Reddit post as I have the same issue and looking for a solution:

Recently in the past month or so, the Del/Delete key has stopped working in Firefox's Save As dialog box popup. Literally every other key works fine system-wide, and Del works in everything but Firefox's Save As box.

To elaborate... Opening up the Save As box for anything in Firefox—a page, a file, an image, etc.—and trying to use the Del key to delete characters in the filename field just doesn't work. Backspace works fine, all other keys work fine.

The only way to get Del to work in that scenario is by pressing Shift+Del instead, which is odd because it didn't used to be like that.

I know the obvious answer is "Just don't use the Del key to edit a filename when saving files in Firefox" or "Use the backspace key insted", but I've been doing it this way for so long that it's pure muscle memory at this point.

I've tested/confirmed that the Del key stops working this way in regular Firefox, private windows, and troubleshooting mode, so I don't think it's an issue with addons or extensions. I can't pinpoint anything else on the system that might be causing it either; it really does seem to be an inherent Firefox issue that's suddenly popped up.

In previous versions of FFox when a file was being downloaded, a file download window opened for each file. Is that feature completely gone or is there still a way to open a window for each file?

I have a new MacBook Pro M5, with MacOS Tahoe Version 26.5.2, and currently running Firefox 153.0. Over the past few days, I've noticed that the Fn-Delete (forward delete) is not working in the file name field when downloading a file from the internet. Fn-Delete is working everywhere else.

I'm not certain if this started when I set up the new computer, updated the MacOS or updated Firefox. I'm pretty sure all have occurred within the past couple weeks.

Thanks.
