Firefox Support Forum

Under Ubuntu. If an application is set to be the default file handler for a certain type of file, Firefox will allow you to open such a download directly in the application. To do this, it saves the file in a temporary location, and then hands over to the application. The problem is that the location firefox uses under Linux is /tmp and modern snap and flatpak desktop apps are not allowed to see /tmp.

For instance, a .deb file is an installable software package. Ubuntu naturally uses the Software app to handle .deb files. But Software is a sandboxed snap app, and it won't open files in /tmp

The workaround of saving files and opening them from the app works, but it defeats the purpose of having registered file handlers.

And I do not know how to get firefox to save temporary download files somewhere else. I can't find any relevant configuration option.

I tried editing the firefox launcher:

env TMPDIR=/home/tim/tmp_firefox firefox

but it still uses /tmp

Hello, I found very different behaviour today between chrome,brave & firefox,firefoxdevedition with javascript and button.

As visible on the screenshots the button is created with its attributes GET and target profile.html via jinja2 templating.

But in addition, via javascript, I added a function to post the selected tables to a route called SaveToDatabase.

In chrome the js part gets executed and profile.html is loaded, but in firefox based browsers ONLY the js POST is executed and nothing else happens.

What could the problem here be?

Best regards and thank you in advance.

I am using firefox 91 beta.

after a new installation i can no longer access the website Add idealo.de as a search engine, neither in the add-ons nor in your own sophisticated search engine.

who has a solution for me?

Many Thanks.

when i type something in the address bar and switch to another tab without searching what was written it selects what was written. It is very annoying as sometimes i write what i want to search in two parts so i have to first deselect it. Is there any way to turn this.

I just let Firefox update on my windows computer. I had OneTab open because I was saving my open pages before the update. After the update, OneTab is gone. Not just the data, but even the icon is gone as if I'd never installed it. Is there a way to retrieve the lost information?

Hello, The bookmark sidebar keeps freezing since the new update (92.0b2 (64-bit) preventing me from scrolling down the list. Is anyone else having this issue? I am using Mohave.

Thanks, Sophia :)

How can i automatically sign in with my Firefox account in multiple Firefox profiles? I have like 100 Firefox profiles that i use for different topics and would love to sync them all at once, i was looking for a file that stored the login approved for my Firefox account info to just copy paste that one file in all of my Firefox profiles, but can't really find it.

This is a problem because every single time i have to introduce my email and my password and sometimes it also asks for an email verification code :( .

After syncing two of my Windows computers (10 & 11), I noticed that the Search Shortcuts configuration of the FF Dev browser on one computer (the more recently updated browser) did not sync to the other computer's FF Dev browser. Both computers show that settings/options should sync.

I suppose this is more of a bug report than a question, but if anyone has any advice, I would appreciate hearing it.

Since I have the Tree Style Tab extension, I put this code in my userChrome.css to remove the tab strip on the top: ```

/* Hide tab strip but keep space for window buttons */
#main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar > .toolbar-items {
    opacity: 0;
    pointer-events: none;
}
#main-window:not([tabsintitlebar="true"]) #TabsToolbar {
    visibility: collapse !important;
}
.tab {
    margin-left: 1px;
    margin-right: 1px;
}
:root {
    --tab-toolbar-navbar-overlap: 0px !important; /* fix for full screen mode */
    --tab-min-height: 25px !important;
}
:root #tabbrowser-tabs {
    --tab-min-height: 25px !important;
}
#TabsToolbar {
    height: var(--tab-min-height) !important;
}
@media (prefers-color-scheme: dark) {
    #TabsToolbar {
        background-color: #2B2A33 !important;
    }
}
@media (prefers-color-scheme: light) {
    #TabsToolbar {
        background-color: #F9F9FB !important;
    }
}
#TabsToolbar[inFullscreen="true"] { /* Do not display window buttons space in full screen */
    display:none!important;
}

``` Is there any way to make this block of code to only be activated when the sidebar is on Tree Style Tab? Something like the `#TabsToolbar[inFullscreen="true"]`. Because I can't navigate through tabs if the sidebar is on (for example) bookmarks, or switched off.

It seems the mobile view in Desktop has broken a while back, or something new from ad-networks is breaking it?

When loading pages with ads (tested with AdThrive) on mobile view, it's nearly impossible to browse. When scrolling, it just jumps back to the top of the page immediately. Only after fully loaded, does it kinda work, but then jumps again. Here is an example:

https://cheeseknees.com/strawberries-and-cream-stuffed-french-toast/

Load it on mobile view and see what I mean. I'm reaching out to AdTrhive as well, but not sure they'll care much since it's an emulated view and actual mobile devices work fine.

As seen in the picture, Firefox will put some characters as PingFang SC and other characters as Noto Sans. It seems that the PingFang SC font file has broken.

OS: Manjaro Linux Firefox: Dev edition 92.0b7-1

Today I found that my sync is disabled (it works at least 2~3 months ago)

I click "enable sync" but it just said "working" or something (not sure what exact word it is in English version, the original text is "正在开启同步...")

Then I found a answer at this site said quit and login again might fix the problem

...then I can't login anymore

When click "login" in about:preferences#sync , it jumps to https://accounts.firefox.com/signin?action=email&service=sync

I login to accounts.firefox.com successfully and found the device I'm using (fde 92, check attachment 1)

But the Browser is still not logged in (check attachment 2)

I tried:

• Reset pref.js & user.js
• Delete /weave/ folder
• Disable all addon
• Delete device in accounts.firefox.com and login again
• Delete /startupCache/

None of them works

Any help?

I currently run several environments for Dynamics 365 products. Our clients can choose to use our authentication (ADFS 4.0) or we set up a SSO option for them (normally also ADFS of some flavor). The piece that is similar between both is that the domain they authenticate to would not be the same as the application they are necessarily using. For example my clients have a mixture of on premise and cloud deployments but if they are SSO only pull their tokens from one domain.

Anyways the real TLDR as I can determine is as follows:

Has anyone seen a problem with firefox 92 stripping out headers? My scenario is I have an AD FS server that I use for single sign on with a domain name that is different from the application that it federated with. When I attempt to login using Firefox, the traffic flows as: 1. Hit the app url and get 302 redirected to the IDP 2. enter credentials at the IDP and get redirected to the app url 3. the app has an internal and external claims URL, so the internal claims url 302 redirects me to the external url 4. FF brings up the external url, but does NOT pass the MSISAuth and MSISAuth1 cookies from the IDP 5. The app thinks I've not authenticated, so it 302 redirects me back to the IDP 6. The IDP sees the MSISAuth and MSISAuth1 cookies, so it knows it authenticated me and it 302 redirects me back to the app wash, rinse, repeat for 5 times until AD FS realizes that I've done this 5 times, then it throws an error at me to stop the loop. This was working fine in FF 91 and it currently works in Chrome and Edge. The expected flow is almost the same, except that the app get's the cookies presented to it from AD FS. I was thinking this was something to do with Enhanced Tracking Protection. When I selected Custom and unchecked all the options (I think this disables ETP) I still get the cookies stripped from the header. I re-enabled ETP with standard protections and manually added the URLs using the steps outlined at https://bugzilla.mozilla.org/show_bug.cgi?id=1432644#c27. Is this a bug where FF doesn't honor the settings to disable ETP in V92? The reason I was thinking that ETP was to blame is the IDP has a domain of IDP.example and the app has the URL's of internalclaim.app and externalclaim.app.

I feel like I am missing something obviously here but I can't find it. If I create a CRM deployment using the same domain as our ADFS servers it works fine. If I use what our public designation is, it fails. SSO obviously fails. It only started after upgrading to 92 and that is consistent amount all of our clients. I have tried to go through every advance config that was touched with the 92 upgrade and nothing there seems to help. We compared our UAS to a friend of ours who is not having issues since the 92 release and they look the same. If this was a system 92 problem I would expect the internet to be exploding by now but it is not. It makes me think there is something I am missing in our fundamental set up but for the life of me I can't identify a missing update, compatibility issue, known issue blah blah blah. Edge, Chrome, Safari they all still work fine. It is just the Firefox 92 update that all of a sudden killed our authentication.

I always have to close all Firefox instances from task manager all the time and then open firefox -p and delete users. It creates them again and again. Is there no way to stop this?

When viewing extensions in the overflow menu, items become cutoff. Sometimes a scrollbar will be displayed, allowing you to view the rest. At other times, you are not able to navigate to the other information at all. I tried to use ctrl + (+ or -) to try and zoom out, but only the size was able to become bigger or smaller, not the scaling.
