Hi I keep getting this error on Firefox. I did disable all my extensions prior to this image shown to see if it was an extension causing an issue to no avail. I also looked for an update for Firefox and saw it was up to date. I also attempted to refresh Firefox which was a successful refresh however the error persisted. After refreshing I fully uninstalled Firefox and then reinstalled however the issue persists.

This error is shown however if I refresh the page sometimes the page freezes as if it lost connection and sometimes it reloads as per normal with the video playable.

Hi,

I want to print some labels, but when I print them, they always com sideways. Even when I change them settings on the printer, to print it not sideways.

I tried using the new profile system, but it totally F**d me over. I can no longer access I site I've been using for years because the profile system kicked me out of it and now I cannot get back in because Firefox is telling me it's an un-secured connection. I don't care. I put it on the exception list, but that did not work to let me back in again. Help, please.

Hello Mozilla Support Team,

I am experiencing a critical Firefox Sync issue and would like to request your assistance.

I recently installed Firefox on a new Windows system and signed in using the same Firefox Account that I have used for a long time. Although my account shows recent activity (last connection around mid-February), none of my synced data has been restored on the new installation.

The missing data includes:

Saved passwords (logins)

Bookmarks

Firefox preferences/settings

I have carefully checked the Sync logs (about), and they indicate that collections for passwords, bookmarks, history, and preferences do exist on the Sync server. However, the new profile does not download or apply these records, and Sync appears to treat the new local profile as authoritative.

I suspect that repeated sign-ins and sync attempts from a fresh profile may have caused my previous data to be overwritten or made inaccessible, even though the server still reports existing collections.

Given the importance of this data, I would like to ask:

Is it possible to restore my Firefox Sync data (passwords, bookmarks, and preferences) from a snapshot or server-side state from approximately 20 days ago?

Is there any way to force a full restore from the server instead of uploading the empty local profile?

Are server-side backups or recovery options available in cases like this?

I fully understand that Firefox Sync uses end-to-end encryption, but since the data was previously accessible under the same account, I am hoping there may still be a recovery option.

Please let me know if you need any additional information, logs, or identifiers from my account or device to investigate further.

Thank you very much for your time and support.

Kind regards, [edited email from public community support forum]

Recently the use of Ctrl+D to open the Edit Bookmark box (save bookmark) stopped working properly: On first press of Ctrl+D nothing happens, then if I press Ctrl+D a second time, the box appears??? The weird thing is that once the box appears with the second press, any subsequent use of Ctrl+D will work the way it should. Windows 11 with no new extensions etc.

I only cleared the cookie for Blogger and cleared my cache. I was logged out of Facebook, Grok, ChatGPT, Linked in and X and possibly more websites I haven't visited yet. I wasn't logged out of Google I don't think. I don't use Google for logging in anywhere and cookies aren't cleared when I close my browser.

Hi,

I’m experiencing the following issue:

When I open Password Manager (about:logins), the page is completely blank.

This problem started about three months ago, after I updated Firefox to a newer version.

Currently, on the about:logins page, I can export all my accounts and passwords as a CSV file (so the data clearly exists), but nothing is displayed on the page itself.

I also tried importing the same CSV file (exported from about:logins) back into Firefox. After importing, all accounts and passwords appear in the left panel. However, when I click on any item, the right panel is still blank. If I close the page and open about:logins again, the items still do not load.

My current Firefox version is 147.0.

How can I solve this problem?

Thanks!

ok when I up date my lap top and it is time to go pay my bill I have to verify who I am they do not recognize me????? It' a pain in the ass...... I have to get pass numbers etc. to prove who I am. M. Rivero

Доброго времени суток.

Недавно столкнулся с проблемой невозможности установки файлов из различных источников (не только с одного конкретного файла), сами файлы тоже разные, от папок до установщиков. Всегда один и тот же паттерн, сначало загружает 30кб, потом загрузка приостонавливается, проходит 3-4 минуты и он обозначается как "не удалось". Пробовал решить проблему, ничего не вышло.

Firefox was using GOBS of CPU, so I killed the master process and relaunched, but after launch I couldn't get any pages to finish loading. I then hoped to copy URLs from tabs and paste them into Floorp (which is working fine, as is Chrome), but I couldn't even snag the URLs (dominated by YouTube pages). I ran a full-system virus scan, finding nothing. The most recent Windows-11 update on 2026-Jan-15 isn't recent enough to be a likely causal factor. Firefox has about twice as many extensions as Floorp, but it was running fine until late yesterday (it's now after 3AM). I couldn't get the extensions page to load, so I've attached a screenshot of C:\Users\Mike2\AppData\Roaming\Mozilla\Firefox\Profiles\oa7ou5xk.default-release-1715337056307\extensions There are several other profiles, but there's very little in them (one profile with a times.json & several profiles containing a parent.lock file)

Processor Intel Core i9-9980HK CPU @ 2.40GHz (2.40 GHz) Installed RAM 128 GB System type 64-bit operating system, x64-based processor MSI GT75 Titan 9SG

If I reinstall, will I lose all of my tabs?

Hey folks!

Thanks for taking the time to look at this, simply put I am using the 'workspaces' app in windows power toys which allows me to open windows in specific configurations to make a workspace. The app allows me to open other apps with CLI args, so I can open Firefox to a preset url, or even predefined set of tabs.

This has got me wanting to use my firefox tab groups as a way of opening "dynamic" windows in my workspace. All that would be needed is a way to open a specific tab group from CLI, or more specifically a CLI arg that I can input into power toys workspace.

Please let me know if there is a way to do this. I checked the Firefox CLI [https://wiki.mozilla.org/Firefox/CommandLineOptions|documentation] and didn't find anything though.

I have entered in exceptions for a web page that Firefox continues to block....I have gone through your steps 4 times now...one time out of 4 you actually let the web page through....since then you don't again...what is wrong with your system? as I am not receiving a download link from the intended exception due to the fact you are not honoring it....

Edge" (or some Microsoft product) repeatedly tries to preempt Firefox, my default browser, loading my default page: Yahoo.mail. It happens inconsistently, and in different manners, hard to describe. It happened on my desktop and also on my laptop. It seems very aggressive, but right now the start-up was normal

Although I remain logged in to sites and cookies show in DevTools, the cookies list in settings>privacy>Cookies_and_Site_Data>manage_data shows as empty, no cookies listed.

In troubleshoot mode, the same blank list. I haven't changed any settings. network.cookie.cookieBehavior is set to 1 I'm on windows 10 Home 22H2

The update to 147.0.1 seems to have caused it. Please advise.

I deleted coockies and since then (even though the Settings appear correct) every time open a web site I hace to accept cookies and re enter my log in. Nothing is rememebered. I evern have some sites opening blank (without my saved options) but on my home computer the same user name and password displays the data that i missing on my work computer. I exported passwords, deleted and re-installed Firefox but there is still the same problem.

Help please!
