Hello all.

I chose "Use Adobe Acrobat Reader" for open PDF in settings and it works fine until I closed Firefox and open it again. The setting bounce to "Open in Firefox". Then, I tried choosing "Always Ask", closing Firefox and opening Firefox again. The setting preserved as "Always Ask" and did not bounce to "Open in Firefox".

I checked handler.json in user profile folder after I chose "Use Adobe Acrobat Reader" for PDF, action is 4: {"defaultHandlersVersion":{},"mimeTypes":{"application/pdf":{"action":4,"extensions":["pdf"],"handlers":[{"name":"AcroRd32.exe","path":"C:\\Program Files (x86)\\Adobe\\Acrobat Reader DC\\Reader\\AcroRd32.exe"}]}},"schemes":{}}

But then after restarting Firefox, it changed to 3: {"defaultHandlersVersion":{},"mimeTypes":{"application/pdf":{"action":3,"extensions":["pdf"],"handlers":[{"name":"AcroRd32.exe","path":"C:\\Program Files (x86)\\Adobe\\Acrobat Reader DC\\Reader\\AcroRd32.exe"}]}},"schemes":{}}

Checked handler.json with "Always ask". Before and after restarting Firefox, action is 1, which is expected and correct.

Some other colleagues reported the same issues as well. I am thinking if this is a bug from Firefox.

Some more notes here:

  • The issue only happens to PDF, for other Content types, all good.
  • Already disabled all plug-ins and extensions.
  • Tried refreshing Firefox in safe mode
  • Tried choosing another external PDF reader Foxit
  • Firefox version is 140.0.2

Some screenshots are attached showing where it is.

Hope someone can help on it. Thanks in advance.

All of a sudden Firefox started to use alt+number (e.g. alt+3) to switch to that tab (i.e. tab 3 in my example).

Why? How do I disable this? It prevents me from typing any of the special characters that are located on alt + any number key. E.g. I can type the at-sign, not the dollar, or any such character which requires the alt-modifier and a number.

Ok so I usually choose these option to remember history and from time to time delete Browsing & download history and Temporary cached files and pages.

https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-28-08-45-55-a5277f.png

Note: I have "Open previous window and tabs" ticked in general settings which also has a restore previous session option in the history menu. This brings back previous session with tabs etc as is when I close FF. https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-28-08-45-51-cf2daf.png

I thought I could automate this on exit but don't think its working right. So I change the option to "use custom settings for history" and tick all three options:

Remember browsing and download history Remember search and form history Clear history when Firefox closes For "Clear history when Firefox closes" I ticked Browsing & download history and Temporary cached files and pages. https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-28-08-45-43-b10213.png

The issue is the restore session option is missing and FF opens with all previous tabs gone. I am frankly not even sure what else is missing such as cookies, site data etc. Is this meant to work like so?

From a week ago, for no apparent reason, I get "403 Forbidden" when I try to read articles on seattletimes.com using my prescription to the site. It's a total block of the site.

After rebooting, the site is OK until I log in, as needed to read particular articles. Then nothing is accessible any more.

The trouble is the same on all my laptop/desktop computors, which all have Firefox and are in sync with it, and once I log into the site on one of them it's blocked on all. But this doesn't affect my android phone, on which every article can still be read.

This is clearlly therefore a Firefox problem.  I'm worried that I'll have to switch out of Firefox to some other browser.  This is unreliable behavior.

Previously, recent websites, and pinned websites would show on the Firefox Home / New Tab page. Now, it is completely blank, except for three rows of blank boxes, which are unresponsive, a search entry, which works, and a weather app with menu.

I can't access "settings." When I click "Settings" a faint shadow around the edges of my screen appears, but the actual page does not load. Sometimes, Firefox itself won't open for several days so I've had to start using an alternate browser when this happens. Is this a known issue?

Since updating Firefox to 140.0 (I am currently on 140.0.2 on macOS Sequoia 15.5), when I launch a Firefox window using the non-default profile, that window is not able to load any pages. When I try to close that window, it either requires me to "force quit" it, or if I wait long enough, the Firefox crash reporter appears.

When I first create a new profile, it works. However, after closing that window, or restarting Firefox, the non-default profile can't load pages and eventually crashes.

Things I have tried:

  • Deleting all profiles and re-creating them.
  • Using new-style profiles instead of the ones managed by `about:profiles`.
  • Visiting a local address using an IP address to rule out DNS issues.
  • Starting with the non-default profile (using the new-style profile switcher)
  • Starting the non-default profile in troubleshooting mode (the browser crashes when trying to restart)
  • Clearing the startup cache in the non-default profile (the browser crashes when trying to restart)
