Firefox Community Forum

So the other day I spent hours deleteting old bookmarks (and bookmarks that have for some reason duplicated) from firefox browser, alongside tagging them and other housekeeping things but when I went back into the manage bookmark page all the things I did yesterday had reset so all the bookmarks I had deleted came back all the tags (but one) I made gone. So how do I stop bookmarks resetting to what they were?

After 11 year I suddenly can't access my Wordpress blog on Firefox. I have to use Chrome to access it - with no problems. I have been on Ubuntu Elementary for years years and have never had difficulty accessing my blog. I have uninstalled and re-installed Firefox twice, I have emptied my entire cache and cookies. I also tried to empty my DNS on Ubuntu Elementary but my version doesn't have DNS. The problem started 24 hours ago.

HI, After upgrade to Seqouia 15.6.1 an extension for developing Oracle APEX applications breaks Firefox. It is the only extension I have installed. Console information is not really that helpful. Maybe you can make some head and tails about it.

Whhhhyyyyyy am I suddenly unable to access certain parts of the Delta.com website?? I had no problem with the website re my outbound flight and now I can't access any info on my return flight on their "flight details" page. They had to send me a screenshot of what they had on their screen because I cannot get it on my own screen. I am worried as I get closer to my departure date that I still will not be able to access my flight info and will not be able to check-in! They told me to change browsers! Help! 😳

Hello Community - I am Darren Chaker and am inquiring whether Firefox or any other Mozilla browser has a built-in feature for a permanent, secure erasure of browsing data like cache, history, cookies, and site data. Specifically, I'm looking for a function that doesn't just delete the pointers to the data but actively overwrites the data on the storage drive, making it unrecoverable even with forensic tools.

I consult with various people and organizations where who want to only perform a limited function within the browser in lieu of running an entire secure wipe throughout the entire computer using software to conduct a multi-pass wipe, or Cryptographic Erasure where the encryption is destroyed.

Some clients in the legal, financial, and government sectors require data security and sanitization dictate not just best practices, but often legal and regulatory requirements. For these professionals, when data is marked as "deleted," it must be truly and permanently gone. The distinction between a standard file deletion (which often just removes the file system's reference to the data) and a secure wipe is critical.

Currently, I rely on third-party software for these tasks and often recommend solutions like Cryptographic Erasure for sanitizing entire drives by destroying the encryption keys. However, this is for the entire storage device. My question today is focused specifically on the browser level.

When a user selects "Clear Recent History," does Firefox perform any overwriting passes (e.g., a single-pass zeros write), or is it a standard OS-level deletion? If this functionality doesn't exist natively, are there any trusted, Mozilla-vetted extensions that offer this level of secure data sanitization for browsing activity?

Having such a feature natively or through a recommended extension would be an invaluable asset for users who handle sensitive information and require an auditable level of data destruction within their browser environment.

Thank you for your time and any insight you can provide.

Best to everyone here, Darren Chaker

I'll be honest, I have strong ethical objections to "generative artificial intelligence" (genAI) on a range of issues, and I have seen no sign that the industry is capable of, let alone plans to address any of them. But I'm not here to debate genAI, I'm here because I require a work enviroment and tools that make it as easy as possible, preferably default, to avoid genAI.

I'm deeply disappointed that the Mozilla Organization has decided to add genAI to label tabs in Firefox. Even if I didn't have ethical concerns, I would still be disappointed at the bogged-down performance and genAI hallucinations that make this change categorically a downgrade.

I respect other users right to do things I find harmful, and the Organization's authority to make decisions. I treat genAI much as I treat smoking, everyone gets to make their own choices, but I have the right not to be exposed to second-hand smoke. Having genAI options default to on is like having somone blow smoke in my face, and when they can't be turned off, it is like having an acquaintence who insists on smoking in my home: I won't have them over (use their software) any more.

I'm in the process of kicking the people who smoke in my house out, and minimising my exposure to "second-hand smoke" (unwanted genAI). I've been a Mozilla user and proponent since the Organization was founded, and was a Netscape user before that, so I don't want to lose an old friend... but I am looking into other options.

Hi. I have been using Firefox with DuckDuck Go extension for maybe 6 - 7 years now. This worked well with Gmail, no issue. Since July 2025, an update came through in Firefox and now an issue with Gmail. The mail opens properly but after 5 to 20 minutes the responsiveness slows down to stop. A pop up above the mail view states that Firefox is causing the slow down and there is a button to press to stop the issue. When pressed, the mail screen is frozen and I have to exit the G mail and restart. I have uploaded the most recent version of Firefox.

Firefox Ver 143.01.1 64 bit.

Windows 11 Pro

Cannot find the version of G mail used, but it is the latest update.

I have contacted G Mail about this issue as well.

How to resolve the issue, going on since sometime in July? I was hoping that a recent update by Google or Firefox would resolve, but it has not.

Very annoying especially when corresponding or trying to load attachments. Please help.

saw a post that recommenced to installing K-Lite Codec Pack would help so that i could set 1440p on Twitch because the option is greyed out for me. after installing it, twitch gets hung up and never finishes loading. it loads in a private window, and on edge too. i turned off the few extensions i have but that didnt help either.

i uninstalled the codec pack but im still getting the issue.

if i hit F12 i see theres an error Loading failed for the <script> with source “https://assets.twitch.tv/assets/6411-9f5e77558af00b1acec0.js”.

thnx!

Hello, FF support forum,

I think I have seen a Container retain my login to a site when I open it again after closing it. Is there a way to configure Containers so that they are mini versions of the dump-cookies-temp-data when I close Firefox entirely? I would so love that functionality.

Regards, G.W.

The very first time I opened Firefox and tried to do a search I got a hijacker:

https://search-owl.com/?path=firefox/newtab&u=895622cd6e29c107&subid=11118&channel=18

Why?

I did a scan with both Malwarebytes and with TotalAV, no detections.

I stopped using Chrome and Brave because I had another hijacker (Yohoo!). I used Malwarebytes to quarantine and delete that because my paid subscription to TotalAV didn't find it. Now I'm stuck with an all new different hijacker upon installation of Firefox.

Basically, i need my tabs restored. I tried lurking around. I lurked moar. I chatGPT it. I even tried to find tech support. Nothing helpful ¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯

I have a lot of tabs that i need and they accumulated over months of my chrome usage. I successfully restored history and other things, but not open tabs. Well, how do i restore them or do i have to manually open all of them?

Note: i deleted chrome already

I was on the ESR channel and after the recent updates to 142.01 or 141 the ESR is missing from the about Firefox. I had got the tab groups option a few updates back and liked it. This latest update changed how a tab group collapses, instead of showing only the tab group name and collapsing all the tabs it leaves one open wasting space when I have several other tabs open. At least I don't see any sign of the annoying AI junk getting in the way yet. I thought you had a choice to stay on the ESR channel according to this link and others. https://support.mozilla.org/en-US/kb/firefox-support-windows-10-end-support I'll probably be forced to update to Windows 11 to do my taxes next year but I thought at least I could stay on the ESR channel to avoid new features getting in the way.
