I moved to the Firefox flatpack after the Debian version couldn't display the code inspector/ web developer tools anymore (it was blank amid other likely javascript-based rendering errors). I only include this context in case some one else has the issue and searches for it.

I want to sync all my tabs from the Debian version to the flatpack version and similar to this solved issue I cannot access those tabs from the firefox view. However I am also unable to access these tabs from the sidebar. I am only able to access these tabs from the account menu but this would have me open each tab individually which is not feasible for me.

Is there a way to fix the "Check your internet connection If you’re using a firewall or proxy, check that Firefox has permission to access the web." error that comes up in both the Tabs from other devices sidebar and Firefox View menu?

I have used Thunderbird for a few years and never had a problem until now. I am on Linux Mint and I updated to Thunderbird 60.2.1 I just launched it and the calendar (lightning) is no longer compatible with this version, this is stupid, the calendar feature is an important and integral part of any email system! I have six months of appointments, tasks and events just wiped out why update when something important like the calendar is not going to work. Can this be fixed? if not Thunderbird is no longer fit for purpose.

I don't want to have to start messing around installing an earlier version

Just like the Android version of Firefox does! It opens the new tab(s), but load each tab at visit!

Desktop Firefox also does this at [History / Restore Previous Session]. All the previously opened tabs are opened again, but each of them only loads at visit.

This is I would like to have as default behaviour with newly opened tab(s) in Firefox. > Tab opens. > It hasn't loaded yet! > At visit it loads the content.

PS: I tried, but didn't work: > about:config _ browser.sessionstore.restore*demand (switch) > Addon _ LoadTabOnSelect 3 (But it worked weirdly.)

"This profile was previously synced to a different account To keep your data organized and secure, each Firefox profile can only be synced to one account. To sign in using xxx@xxxx.xxx, create a new profile."

So I deleted my old mozilla account since I abandoned the email that it was linked to, but when I tried to sync with my new account I get this. Is there anyway to do this without having to make a new profile?

I tried making a new profile and copy and pasting my profile into the new one, but still get the same pop up. I guess there's something in my profile that says it's been synced before, is there anyway I can find that and delete it or change it?

Hello, I have a problem: After an automatic update of the language packs, parts of the Firefox menu (version 126.0) are displayed in EN. Parts in DE. Seems to be related to the update... how can I change this again? I have already changed the language settings. Didn't help...it appeared after an automatic update on May 28. Thanks for an idea :)

I am developing a django website.

The login on the default admin page is not working when I am testing locally on my mobile. I assume it is because the connection is http (and not https) in order to protect the users (which is a good thing).

I assumed this is the problem, because on chrome, I got also blocked, but I got this hint.

Therefore following 2 stories:

• As a user, I wish I receive a feedback when something is blocked by the browser, so that I understand what is happening.
• As a developer, I wish I could allow login on whitelisted sites (local websites like 192.* ?), so that I can test my website on android without creating self-signed-certificates.

If my assumptions are wrong (but the server did not receive any call), do you know, how I can visualize the network calls on android?

FYI - I've been using T=Bird for years so not a noob. Developers: This is an important security feature and should be repaired.

Just "upgraded" to 18.04 Xubuntu 32-bit which includes T-bird 60.2 and experienced the following. (no add-ons) New messages were being marked "read" immediately when moused over or selected, no delay. Not usually a problem because there was a settings in Tools>Options>Display... The problem is that with 60.2 this Tools feature is gone (on my install) and there is no access to the unread/read delay setting. I solved the problem by going into the flags ("Here be Dragons", accessed via Preferences>Advanced > Config Editor) Warning! Do not use the config editor unless you are confident you won't damage anything. Open Config Editor> Search: "message_read" no quotes You should see the three results / flags below. To enable delay change "read.delay;false" to true. This is done by either a double click or right click > select Toggle. After you change it it will be bold, that's normal. It's just to let you know it was modified. Leave the other two as is unless you want more or less of a delay then change the number at "delay.interval" mine was 5 so it's fine. Leave "read.auto" set to true. Close the editor and it's done.

(this is how it looks when delay is disabled) mailnews.mark_message_read.auto;true mailnews.mark_message_read.delay;false mailnews.mark_message_read.delay.interval;5

(this is delay enabled) mailnews.mark_message_read.auto;true mailnews.mark_message_read.delay;true mailnews.mark_message_read.delay.interval;5

That's it. Your messages will now change from unread to read in 5 seconds not instantly. If you have the Tools>Options on your system by all means avoid the Config Editor but since it's missing on mine it's probably missing on others' as well. I searched for a solution before posting this and didn't find it so hope this is helpful to someone.

First off, apologies - I don't know if this is a YouTube problem, a Steam Deck problem or a Firefox problem. I haven't been able to figure out the cause of this problem for months so I'm trying you guys because you're more responsive than YouTube has been so I'm really hoping it's a Firefox problem.

Basically since early June I've been getting "an error occurred" errors for YouTube videos of approximately an hour. Longer videos and shorter videos tend to play fine, but I get the issue with videos under ten minutes sometimes as well.

This only occurs in Firefox on my Steam Deck (SteamOS). Other browsers and other devices are fine.

I have cleared my cache, cleared cookies, disabled extensions and logged in and out of YouTube to no avail. The problem still occurs in troubleshoot mode and updating Firefox hasn't fixed it.

Would appreciate any troubleshooting tips and again, apologies if this ends up not being a Firefox problem, I just don't know what else to try at this point.

Hello, editing Bookmarks is a manual process within Firefox Bookmarks. I would like to export sub folders and edit them on my preferred desktop text editors, then re-import said edited Firefox Bookmarks folder.

I have tried Firefox sub folder:

• dragging and dropping to Desktop, however fails
• copying/pasting to Desktop, however fails
• AI promises the world like a conservative politician's gish gallop, but nothing works and wrecks the current setup.

I have exported the entire Bookmaks.html file, however editing html to text, then somehow only text remained without urls. So now I have restored from an old 3rd party's bookmarks and need to clean what Bookmarks are left. Sub folder management would be easier than entire Bookkmarks.html.

Hello,

After upgrading my Thunderbird install to version 60.2.1 on my Xubuntu 18.04 machine, I cannot access my mail anymore, because there seems to be a problem with passwords.

Symptoms:

- When starting Thunderbird, I get an "Enter your password" box for each of my accounts even though I had my passwords saved.

- When I go to Preferences -> Security -> Passwords -> Saved Passwords, the list is empty.

- When I try to enter a password and save it, it does not actually get saved and Thunderbird will ask again soon after.

- The following line is logged to console a whole bunch of times:

JavaScript error: jar:file:///usr/lib/thunderbird/omni.ja!/components/crypto-SDR.js, line 179: NS_ERROR_FAILURE: Couldn't decrypt string

Other findings:

- Downgrading Thunderbird to 52.7.0 fixes the problem. The old saved passwords just reappear again and Thunderbird has no problem logging in.

- Starting Thunderbird 60.2.1 on a Windows 10 box with exactly the same profile folder works fine. It can read the passwords and access my mail accounts.

Can you please tell me what to do to fix this, so I don't need to keep using an old version of Thunderbird just to access my mail?

Thanks,

I have started posting bugs of Firefox in Bugzilla for almost 6 months now(though the number of bugs is 3). I have noticed that the bugs really had no response for nearly then(almost 6 months), so is it the way bugs are handled?, like they take long time to address( just asking as I though the process to be relatively fast) or is it something that I might be doing wrong in reporting a bug. I searched online and have been looking at assigning the bug( what I understood). So, how to do it if there exists something like assigning and will it increase the movement on my bugs??

On Firefox 124.0.2 (on Ubuntu 22.04.4 LTS), when I click a download link on a web page, Firefox doesn't download the file. I tried disabling all add-ons, but that did nothing. However, I found that when I deselect "Ask you where to save the files" in the browser's Settings and then click the link, it downloads the file to my Downloads folder. Can someone please point me in the right direction to find a solution for this?

I've installed Nightly the same way I have for years on my latest Fedora 33 install—i.e., download tarball, extract into /opt, set appropriate chmod and chown, make .desktop file, etc.—but certain videos certain videos on certain sites refuse to play. A Fedora discussion discussion led me to think it's how Fedora 33 may sandbox apps; I haven't yet had any hits on solutions in the Fedora groups, so I thought I'd ask here, since I can't be the only one with this issue.

Any help would be greatly appreciated!

On Firefox 128.14.0esr (build 20250811113756), Linux/X11, the setting browser.tabs.hoverPreview.enabled does change back to "true" every few days, or perhaps browser restarts.

How can I turn off tab previews reliably?

I reinstalled thunderbird and cleared the profile folder. Then when I login Gmail, after the OAuth, it tells me "Unable to login at server. Possibly wrong configuration, username or password."

This only happens to Gmail. I also tried Outlook and this didn't happen.

I then tried running thunderbird in the terminal to see what it outputs: (image 2)

"line 232: Script terminated by timeout"

Technical information: TB version: 128.5.1-1 (arch linux aur)

Ubuntu 22.04.5 (kernel 5.15.0-153) Firefox updated from 142 to 143 automatically by snap.

In version 142 and older, html file with image source pointing to local (remote) network image file displays properly.

In version 143, this does not work anymore. I tried changing the image to point to a local computer file and it works.

In verion 143, If the link to the image is typed directly to the address tab in firefox, it works.

Perhaps some config setting need to be changed? Hope somebody can help.

Thanks in advance.
