Firefox cannot access my file system

more options

Firefox cannot access my local filesystem. When I open a PDF in the browser and click the Save button, nothing happens. When I click a "Browse..." button to browse the filesystem and upload a file to a website, nothing happens.

This issue does not happen in Google Chrome. This issue persists in Troubleshooting Mode.

Please help! I'd be glad to provide more details as requested.

Is that a change? Did it coincide with an update? Can you open a local file with File > Open File (ctl+o)?

You can try Firefox from the official Mozilla server if you currently use a version from the repositories of your Linux distribution to see if it behaves differently.

It is a change; this started happening yesterday, and I had been using Firefox with no issues for a couple of days before that.

Checking my Firefox version, I don't think it coincided with an update, as my version is 99.0.1, and I'm fairly sure this is the exact version that came with the OS (I freshly installed Ubuntu 22.04 a few days ago). If there is a better way to take a look at Firefox update logs to see if it updated when the issue arose, let me know.

Ctrl+O does not bring up any dialog.

I'm using Firefox on a fresh install of Ubuntu 22.04, so this is the Snap version of Firefox that shipped with the OS. As I understand it, Mozilla developed this Snap so it should be considered an official Mozilla distribution of the browser.

I'll try uninstalling and reinstalling Firefix as a Snap, then if the problem persists I will try to reinstall with the tarball you linked.

As a note—and maybe this is important—I was able to download the tarball from the link you sent. I immediately tried to download an image (Save Image As...) and this produced nothing. Weird.

I tried reinstalling Firefox as a Snap, but the problem persisted. I've just now installed Firefox from the tarball, and the problem is solved.

It's great that the problem is solved but I do not want to have Firefox installed in this way, as it will make updating the browser much more difficult. I wish to have a self-updating installation of Firefox.

How should I proceed? Should I try installing Firefox with self-updating packages other than Snap (say, .deb or .appimage)?

Can you just do what cor-el asked and install from Mozilla to see if you have the same issue.

I did.

I then proceeded to explain that while installing from Mozilla does fix the problem, it is not a viable solution for me as manual updating is far too tedious.

So, do you have any productive suggestions on how to proceed?
