Firefox Community Forum

woke up yesterday and suddenly my browser is largely non-functional.

When opening a file browsing window to upload or attach a file, where firefox would normally open my OS's file browser (Dolphin) it now opens a hideous firefox tab with extremely limited functionality (no file sort/ search/ open, or access to most of my system), and the Download toolbar is now completely broken. Clicking a file opens a little dialogue box that asks "Open with System Handler?" and does nothing upon clicking OK. Nothing also happens on clicking the folder icon to the right, which would normally open a Dolphin window with the file in question selected.

I did not really know what happened but every time I opened home page, it did not load. It was working before but suddenly it didn't. I have tried writing "about:home" into search bar and it returned nothing. Just a blank page and an empty search bar.

I've checked the settings and it should be fine. Nothing wrong with it. I've checked the flatpak version and its ok. I was able to open my home tab.

I am using Firefox 148.0.2 (64-bit) Debian .deb.

I really enjoy using the recently added sidebar, but I want to put it away temporarily while watching videos. After some digging around, I finally found the simple keybind for expanding it (ctrl-alt-z). With the 'hide tabs and sidebar' option toggled, I'm able to open and close it at will, which is exactly what I wanted.

However, whenever I do this, the sidebar snaps to what I assume is its default size (picture 1). I usually use it at minimum size (picture 2,) such that only the icon of each tab shows. I tried to readjust it, but it seems to not snap to this size anymore unless I disable 'Hide Tabs and Sidebar.'

For now, I'm just going to temporarily toggle that setting on when I want it out of the way, and manually fix things later. But, is there a way I can have the best of both worlds? Can I make the 'default' the sidebar snaps to the minimum size I usually use from Picture 2?

Thank you in advance.

The grammar-checking extension "Verificador Ortográfico para Português do Brasil", licensed as GPLv2, has a link that redirects to a SourceForge category listing. It is nowhere to be found there. It has a contact email, and I've sent a message to them asking for the missing information.

The MPLv2 license requires disclosure of the source code, and so does the GPLv2. What can Mozilla do about it?

I'm running Linux devuan: Linux MikesPI 6.1.93 #1 SMP PREEMPT Mon Dec 8 02:37:53 CET 2025 aarch64 GNU/Linux and Firefox 140.4.0esr (aarch64).

For years now I've been downloading and saving Yahoo quotes as csv, now for the last week Firefox wants to save page image poping up an extra window that must be refused before I can continue using Firefox. Hopefully someone can tell me what new option in about:config can be turned off to stop this. Thanks, Mike
