File Associations Keep Changing

I still am going to use Firefox. I just won't download anything with it. 😎

I also have this problem. High Sierra with Firefox Quantum installed.

JPG files open in Preview. Want to open in Photoshop by default. Photoshop not listed in Get Info..have to choose Other.

Same here - I've not deleted FireFox but haven't opened it for several days and haven't had any peculiarities since moving (reluctantly) to Chrome.

Not that it matters but, Firefox Nightly is doing the same thing still. 😝

Yeah, user mikeytttt suggested it in february and it works perfectly. From my experience all is back to normal, it's a good fix.

Thank you Leolio_, mikeytttt's suggestion seems to have fixed it for me!

Nice temporary workaround, Yorkie. I'll have to consider that.

No Adobe products here beyond whatever my browser uses. I notice this issue is not apparent when I begin work each morning.

It begins after I've been up and working for a few hours, but I can't narrow down if things are just slowing down in general or if there is one specific action that I become increasingly likely to do as my work day stretches on that sets it all off.

I use Firefox all day at work and for a while thought that there may be a connection there somehow related to saving images through Firefox or taking screenshots, but I'm not able to recreate the error at will so meh... I have no idea.

I also have issues where Preview will not even be an option when right-clicking, which then makes me have to search for preview, etc. Very annoying and it takes foreeevvver for apps to populate when going through that whole "open with" process.

NEW WORKAROUND...

In Firefox browse to about:config and search for setting security.sandbox.content.level

Change the value to 2 (instead of the current default value of 3) and then restart the browser.

Mozilla are aware of the problem and are working on a permanent solution.

Just checking with everyone here --- are we all using Adobe Products?

Hey, I hadn't realized until you mentioned it, but yes: the two apps that seem to keep overriding my file associations are Adobe Acrobat and Adobe Photoshop Elements 11. Maybe there's some shenaniganry going on where Adobe is trying to encourage people to use their software...?

I don't think it's related, I'm not using any adobe software (bought Pixelmator 8 years ago and still use it).

Try mikeytttt's workaround, I never had an issue since I did.
