Firefox used to save unknown files according to the save files setting. i.e. ask where to save files. Now if opens unknown files as text in a new tab.

How can the correct behavior be restored?

Alternately, can the Linux snap be fixed to allow saving of new file types? {The procedure shown in https://support.mozilla.org/en-US/kb/change-firefox-behavior-when-open-file is not present in the firefox 141 snap.

After upgrading my 128 esr to 140 esr, some sites stopped opening. In regular versions, it has not opened for a long time. There are many such sites, for example, qwen3.app or temp-mail.io. It thinks for a long time and finally a message that the time has expired. Chromium is ok.

I have recently encountered reproducible failures when attempting to download files or save pages to local storage. The target directory is located on a mounted NTFS file system with the options umask=007, user=root, and group=disk. My Firefox browser is running under a non-root user account that is a member of the disk group. However, I consistently receive the error message: “XXX could not be saved because the source file could not be read.”

I would greatly appreciate anyone's assistance in resolving this issue.

Recently, when I copy and paste an error message to the search box in Firefox and the first word contains a ':', such as when searching for this error message - "MESA-LOADER: failed to open dri: /usr/lib/x86_64-linux-gnu/gbm/dri_gbm.so: cannot open shared object file" - I get the "Open the mesa-loader link with System Handler?" prompt (see screenshot).

I used to be able to copy and paste such an error before into the search box and it would just work but now the browser defaults to thinking you are entering a URL. This could be because when I start typing in the search box, it immediately relocates what I'm typing to the address bar. Maybe this is the behaviour I need to disable? But how and why is it the default?

Help!

I'm using the AI Chatbots plugin in the sidebar and I'm trying to log into Claude, but the plugin keeps asking for a verification code and Anthropic only sends a magic link email which doesn't work in this situation.

I rebooted my laptop with both firefox windows I had open and possibly a private window too, then rebooted again without touching firefox, and now I can only restore one of the two windows. I checked my recently closed windows in history and there was nothing there at all. Is there anything I can do at all to restore that other window or is it just gone for good now?

<OpenSearchDescription xmlns="http://a9.com/-/spec/opensearch/1.1/">

</OpenSearchDescription>

Does Firefox still support automatically updating the opensearch XML description? MDN still mentions this feature: https://developer.mozilla.org/en-US/docs/Web/XML/Guides/OpenSearch#supporting_automatic_updates_for_opensearch_description

Also, in about:config, there used to be an "browser.search.update.interval" entry that specified the update interval. I can't find it anymore.

If this isn’t the right place to ask, could you point me in the right direction?

I have lost my tabs after the recent update. They used to show all tab groups in toolbar icon as mentioned here (https://support.mozilla.org/en-US/kb/tab-groups) in manage tabs section. Only the groups that were open are retained, the groups which were closed are lost. They contained important tabs which I haven't bookmarked. I didn't see any policy of removal of inactive tab groups after certain time, any help would be really appreciated. I use the desktop app on Linux.

One of the recent updates changed Firefox's behaviour. It now remembers my login status to various sites when I close the browser. For example, if I was logged in to facebook when I closed the browser, I will be logged in when I open the browser and navigate to facebook.com. This was not the case until very recently (a few weeks at most). Is there a way to change this?

I have strict privacy settings, and Firefox should delete all cookies when it is closed. There are no 'exceptions'. I have 'always use private mode' checked for history. Also: I haven't changed any settings recently - something changed in Firefox.

Any advice? Thank you.

I am unable to access about:addons on firefox, and I don't what I should do to unblock. I blocked about:addons myself, but I don't remember exactly how I did that, and now I am locked out. Could you be able to help me out with this?

Tried to sign in to Firefox on a Linux laptop; searched for a password and finally found it under "a" for accounts;maybe my error. Tried to sync. bookmarks etc. from Android phone and it suggest two non existent menu options: Sign in and - i've forgotten; Sync between devices maybe; anyway nothing resembling either was in the menu so it is at least satisfying to know you can delete a browser with no concern that anything useful or even functional is to be missed.

Firefox always auto-fills in the wrong phone number. But I can't find a setting that contains my phone number. How do I change my phone number that Firefox auto-fills?

Hello Firefox Developers,

No pressure for this item.

I would like to request that there be an option to censor or hide the Firefox user information in the Firefox UI and in the Settings section for privacy and security reasons, especially when doing online streams or making online guides.

At least an option to either make it "l.............@..." with an eye option beside it. Like what the password field behaviour is in online forms.

It would be nice if the option were available to the end-users.

Thank you so much.

Hi, I can't seem to find an extension for this.

I have several custom search engines that I can use via shortcuts on the search bar, but I'm looking for a way to select text on a website, click the right button on it and select one of those engines in order to search that text.

I think Firefox was able to do it, but I'm only finding extensions that don't use FF's custom engines, I have to add the engines to the extension itself, manually, all over again, and that's a pain to keep synced.

Am I missing something here? Thank you.
