Firefox Community Forum

Spellchecker does not function, and in my most important projects, Gemini and Substack, no spell checking takes place, I have to switch to Chrome of all things...here in this field spell-checking is taking place...why?

I have spent much time researching this issue, made all the intervention recommended, nothing works, and the failure is 'selective', works on many things, fails on important production browser interfacing.

I value being Chrome-free, please help me solve this issue

Hi everyone,

We are currently working on optimizing the speed, performance, and modern web standards of our online store, where we showcase our healthy chewable gummies

Our goal is to ensure that our website provides a fast, seamless, and completely secure experience for all our users, especially those browsing on Firefox. We want to make sure our localized cart state, user preferences, and session caching align perfectly with Firefox's advanced privacy features and web standards.

We would love to get some general guidance from the developer community here:

1. What are the current best practices for structuring client-side storage (such as session storage and partitioned cookies) to ensure they load with maximum efficiency in Firefox? 2. Are there specific performance guidelines we should follow when implementing dynamic, JavaScript-based layout states so they render smoothly alongside Firefox's tracking protection?

We want to build our site the right way from the ground up, so if there are any official MDN Web Docs or recommended developer checklists for e-commerce optimization, please share them!

Thank you so much for your help and insights!

My problem started approximately (2) updates prior to my current Firefox update after 7-13-26... abouit a month of it now. I have great Malware and Security programs and never have been hacked. However now I have popups, redirects to new tabs advertising something, and Bing search engine came up replacing my StartPage search preference. I have since fixed my default search engine, but as noted below I am having no luck with ad popups and search redirects.

I have gone through Mozilla troubleshooting in Settings>Peremissions and Date>Notifications... and checked off all ad and popup blocking. I have checked entire PC with (2) separate Malware programs and found nothing. I use iObit Advanced System Care and it has caught many things, but it hasn't helped me here either.

I am still on Windows 10 operating system and have never had any problems at all Is there someting in a line item entry stored on my PC that I can look for that is taking over my browser settings? What else can be done to stop these insane ad and popup overlays?

Since the blow up User Id's and Passwords to various sites no longer pop in by clicking in the requestors. I was able to retreive my UIDs and Passwords but I now have to obtain them from the Hamburger, Passworkds, etc. for each site I visit that requires a login. Twice for each site...one foe UID and again for Password. That is currently the worst problem I am facing but other damage was done with the update.

Suggestions for fixes are welcome.

I pressed the backup button to backup my firefox stuff before switching to linux, and now that im on linux the file i was given a docx file, is completely unusable to restore anything, meaning that about a dozen of my accounts are completely lost, I did not do anything to the "backup" file besides put it into my google drive.

When a link from outside Firefox opens the desktop browser, it displays the default home page but does not continue on to the URL specified in the link. This is new for me in V 152.0.6 (aarch64) . Mac OS 26.5.2 (25F84)

I use Firefox on various computers, now I'm setting up a new one, and I don't remember either my Firefox password or how to access it one way or another with my own identity. What can I do?

Hello. uz vase roka mi plays videos without sound on Facebook. I tried to figure out why in the settings, but I failed. on other sites, the sound works. what could be the problem?

I download my share of media using BitTorrent with Pirate Bay. Just lately, every time I attempt to download something I get redirected to a page, https://ultimatesurferprotector.com/lp5.php, that tries to sell me a VPN and I can find no way to stop this or contact them. I am happy with the VPN I have and have no interest in purchasing another. Does anyone know how I can prevent this from happening? Thank you.

Heyo! So, I've had this ongoing issue with Firefox for quite some time around trying to access the Newgrounds website, but failing to do so. I have tried several things such as disabling the enhanced tracking setting, disabling DNS over HTTPS, forcing cookies and third-party popups to be allowed but that does not work what so ever and disabling enhanced tracking is greyed out so it's not even clickable to toggle off.

One thing that did work was to use the built-in VPN, but I really don't want to constantly have to use a VPN to browse one singular site every time I want to access it. So now for the question. Has anyone else experienced this? And if you have, how did you solve it if at all?

When checking out the new features the ' Learn More' link under Tab Groups directs to the article explaining Pinned Tabs, there is no way to get to the explanation about Tab Groups
