Hi,

When editing or annotating a local PDF in Firefox's built-in viewer, pressing Ctrl + S (or clicking the save icon) only triggers a "Save As" prompt instead of saving changes directly to the original file.

Manually selecting the source folder and confirming the overwrite dialog every time adds a lot of friction to reading and annotation workflows.

Could we get a native "Save" (in-place overwrite) option alongside "Save As" for locally opened PDF files?

Thanks!

I hope the firefox desktop browser, supports to protect the profile from getting access by other person, who uses the PC. Whole disk encryption is too heavy, so I want to protect the profile on browser side since you already support master password to protect the 'Password'.

Feature request: For a profile with firefox account loggined. Prompt to re-type the password to open the browser, or you can also lock the browser manually until re-type the password. Then able to access the bookmarks and history, so as the session tabs.

Latest Stable Firefox, windows, over 4000 tabs. Overall Firefox works great for me. but when I restart it to install the latest versions etc, it only restores one active/loaded tab per window. Rest are restored, but in a closed/unloaded state. I usually have 5-20 open tabs per window, and hundreds more unloaded, it's how I work. How on earth can I get it to restore all the open/loaded tabs as they were, not in the unloaded state they default to?

Issue still occurs in a new install with no addons, default settings, under 30 tabs etc. Ditto Win 10 or 11.

Also, how on earth can I get official Mozzilla pages to use Dark Mode??

Network Protocol Error The page you are trying to view cannot be shown because an error in the network protocol was detected. What can you do about it? The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

Today, 2026-10-24, it appears google is blocking me from using most tabs in Firefox. Versions are 115.18.0esr (64-bit) and 100.0b7 (64-bit). Worked fine yesterday. I have various Win 7 versions on my three machines. I've been getting warning messages from google for some time about stopping support for Firefox and I contacted them to get a date, but never received a reply. On one machine, when I start Firefox, it immediately dies. On the other two machines, it only lets some websites run, but not my personal gmail or my HSU student gmail. I was planning to install Win 11 on at least one machine, just have done so yet. I could try upgrading to 115.43.1esr. Yes. I am a bit of a Luddite; I started working in computers in 1977.

which addons use the FF built in automatic tab unload ? I do not want extensions with own method because once an addon crashed and i LOST ALL TABS ! :( So searching or sorting for native tab sleep would be more comforting. thx
