I upgraded my version of Firefox from an ESR version to v129.0.1 on Debian 12. Drag and drop of files from the desktop or the file manager (PCManFM-Qt) into the browser stopped working. It is still working properly in Chrome.

This occurs with several web apps but, as an example, it occurs when trying to drag a jpeg into Roundcube Webmail while composing a message.

No browser console errors are genrated when trying to do this. It occurs in Troubleshooting (safe) mode as well. In apps that pop-up a "Drag files here" target, that target still appears but dropping the file on it does nothing.

Hi! I'm using Firefox 126.0 on Fedora 39.

Pages from Amazon.co.uk load very slowly, incompletely, or not at all. All other Web sites are fine.

I had a couple of certificate-related errors saying that the identity of the site couldn't be verified, but I can't reproduce the problem, so I can't quote the exact wording, I'm afraid.

The same Amazon pages load properly in Chrome on the same machine, and they load properly in Firefox in a VM on the same machine. That tells me network connectivity must be fine.

I've tried disabling all extensions, reverting to the default theme, running in Troubleshoot Mode, clearing cookies and site data, clearing the startup cache, disabling hardware acceleration, and creating a new profile. The new profile helps slightly, in that it loads more of the page before getting stuck. Nothing else helps at all.

I'd prefer not to refresh Firefox if I can avoid it, because I don't want to lose all my plugins and settings. This installation is five years old. Besides, a new profile didn't fix the problem.

What's the next thing to try? I'd really appreciate any ideas.

The increase happened here: /storage/permanent/chrome/idb/3870112724rsegmnoittet-es.files/

79 files taking 590MB created in 3 minutes, out of nowhere. Why were all these large files created?

Using Linux Mint, Firefox 125.0.2

I saw this post https://bugzilla.mozilla.org/show_bug.cgi?id=542690 where it seems implied that it should work, but on LMDE 5 w. firefox 98.0.2 64-bit scrolling horizontally w. touchpad doesn't work for scrolling on pages nor for scrolling the tab list at the top.

As per this issue I reported a while back, I was experiencing odd issue with automatic redirect to HTTPS for some private development sites.

I finally found a fix for the issue. The problem appears to be with DuckDuckGo Privacy Essentials Extension which apparently *may automatically redirect to the http site. In order to prevent this, I added my development sites to 'Unprotected Sites' and this prevented DuckDuckGo from doing the automatic redirect to https.

• - Odd thing is that I had multiple domains pointing to the same web instance and only one of the domains was having this issue with the DDG extension. Both were going to the same IP through a HTTP proxy. The proxy and web server were not the issue. This symptom points to an maybe an issue in Firefox....

In summary, be wary of odd redirects and the DuckDuckGo Privacy Essentials extension if you are doing web development work.

Hi,

is there a config option to prevent the showing of user/pw proposals when opening a website for which user account data is saved? When i'm logging into a website with already saved user data, i get account proposals (as ff saves the data "per domain", say if you have 3 accounts to one website, e.g. a test user, an administrator and a cms administrator, they are all presented where needed content may be...) see pict. I would like to opt out this behavior, as i have more than one website with 2 or more accounts.

The styles look astonishingly wrong, I really think it is a problem on my end, but cant figure out how to fix it, as you can see in the pictures, text is incorrectly sized and/or justified, color gradients are also weird looking, as well as sizing of many elements and tons of other things.

I have tried to completely remove Firefox from my system and reinstalling it, that did not seem to fix it. The reason I think is is a problem of mine is because i was playing with fonts (emojis weren't working on my system,not on Firefox tho, now they are in both)

I don't think the things i did with the fonts did anything to Firefox, since this problem only showed up on Firefox, but since the problem arrived just after a reboot while I was installing and removing the fonts, I think its important to mention.

To sum up I think the problem comes from my local configuration of Firefox, I probably did not delete it all before reinstalling, I am running (Arch btw) a current version of EndevourOS.

The problem is : Some of the time FF just records 0 bytes file and says nothing. I suspect that FF inspect the URL of the links and discard ( perhaps for security reason ) ones that do not begin with HTTP.

The bypass is : One has to copy the link and insert in in the new page of FF.

The solution would be to change FF code.

Thank you.

Hi, Could someone tells me how to deactivate the startup popup upon each firefox start which says (translated) "thanks this is 100th version of firefox, start navigation", or is it to stay until the 1000th annniversary ? Thanks

Hi,

I'm using Duckduckgo as my search engine, but when I type in a search string, it Firefox prepends it with https://html.duckduckgo.com/html/... This opens a search page that doesn't follow my dark theme. When I click on a link, another link is added that creates a link back to the same URL, causing a loop. This never happened before I upgraded to Ubuntu 22.04 & the latest version of Firefox, 100.0.2. How can I change this back?

Thanks!

Whenever I use web-applications that use WebGL or anything similar, they are always distorted. And yes, I have tried disabling Performance Settings, but that only slightly helped.

Hi,

I use Mendeley Web Extension to pull articles and other things from Firefox directly into my Mendeley library. I will usually rapidly read through the PDF file online before deciding to add it or not. For some unknown reason, Firefox blocks the use of Mendeley on PDF file, for security reasons, and I can no longer add them to my library. Most references are only available as PDF files making the add-on completely useless. Is there a security feature that I can disable to be able to use the extension again?

Kind regards,

Mathias

I've checked a couple of the "similar topics" before posting here. I'm not sure if I am having the same problem or something else.

Back Story: I have a "few" windows and tabs open in FireFox. I would finish what I was doing, shut down and then the next time I booted up and loaded FireFox, all sessions would be restored and all log ins honoured (kept). That is: I was still logged in.

(Moving to now) Yesterday I powered up and ALL sites were logged out. About 20 log ins were needed. Hmmmmm... gmail, and the rest.

"Ok... something happened. No problems, things should be ok from now. I've logged in, so all is sweet."

Today I power up: All logs ins lost. Had to go through it all again.

Gmail is throwing security alerts at me hand over fist. Yeah, that is good in some ways. I get that part. But I've logged in.

Seems - my thoughts - that the cookies aren't being saved. But why? I haven't touched them or their settings.

Yes, I did do a clean out of older cookies. But left the gmail ones, and other sites I know I use. I have `adblocker ultimate` installed.

Now I am logged in, if I open the `cookies` and look I should see them there for the sites to which I am logged in - yes?

To be clear: When I am done, I do NOT `exit` FireFox. All windows, tabs, sessions are left. I just shut down the machine. Then next time I load FireFox and they are re-loaded and log ins are maintained.

Hey there,

How can I change the css of pages created by an addon?

(Example-URL: moz-extension://285d678c-ecb3-4003-923d-835fc9d8e0bc/reader.html)

I know how to change normal pages css via different tools like Stylus etc. (or via userContent.css). But this does not work for pages created by addons.

Can you please help me?

Hello, I have been using Firefox as my main browser for more than a decade. One could say i am some Mozilla fanboy, having convinced many of my friends and relatives to use Firefox instead of any chrome based options (Which there are to many these days). It struck me today, as i was reworking some workflow elements in many programs i use daily, that it is impossible to change any key binding in Firefox anymore. I know it has been a while now, and i searched all over the web for an answer or a solution, but at this point it is clear that other than going in the code and recompiling Firefox manually, it is not possible. I stumbled upon the (only) extension that allows to change some shortcuts, but the two that i wanted to change are impossible to configure from it, being disabling only f12 as i would use it for other things but i do not want to lose the dev console and also ctrl+L to open the address bar, it is quite inconvenient and would much prefer to use ctrl+spacebar as it matches many other bindings i am using with other software. There have been many other features that were changed in the recent years that made me start to look for an alternative, as i see features melting away almost as quickly as the user base of the product.

I do understand that one person's problem is not going to change the way a big piece of software is working, but i am wondering, why are the users losing such features as basic as customizing key bindings in a piece of software that used to be so incredibly customizable in the past? Why is the only viable option to anything chrome based losing it's edge over the competition? Is Firefox v150 be based on the chromium engine or will it die before?

Thank you in advance, and no, i don't need the link to the shortcut page, i already have it.

I use the Feedbro-Addon, which creates an own tab. Its url is: moz-extension://285d678c-ecb3-4003-923d-835fc9d8e0bc/reader.html

If I use it as a normal tab (instead of a pinned tab) ... it survives a Firefox restart. But if I use it as a pinned tab (which I want) ... it disappears after a Firefox restart.

I suppose it has to do with it being an addon-page instead of a "normal" page.

Is there a way to make it stay permanently pinned?

Firefox 102.0.1 (64bit), Linux, Sway (Wayland), MOZ_DBUS_REMOTE=1, MOZ_ENALBE_WAYLAND=1 When I hover over a menu item, the hint shows up and the menu disappears visually, it is still there, as I can interact with it (mouse click or enter).

everytime I open firefox, it automatically switches tabs like these which require authentication to log in. even though their password is saved, I am still required to click in sign-in button.

Its really annoying that these kind of tabs get opened automatically, and then I have to switch back. Is there a way to disable this autoswitch or better, let the authentication happen automatically since the password is already stored ?

When I open Firefox after starting my computer, all of my tabs from the previous session are automatically restored, and they take several minutes to load. I don't have the "Open previous windows and tabs" setting enabled. Is there a way to stop Firefox from loading these tabs each time I open the browser?

I'm using Firefox 103 on KDE neon 5.25.
