Firefox Community Forum

Greetings!

I have a few questions if you'd be willing to answer.

There have been some changes and new additions to the croatian dictionary (https://github.com/krunose/hunspell-hr) and as such, the Firefox dictionary could be updated.

Can you confirm that the dictionaries and language packs are separate additions and that the dictionaries are used for spellchecking? https://addons.mozilla.org/en-US/firefox/language-tools/

When is the spellcheck dictionary installed, only when the user installs it or when the user installs a language pack?

In addition, the croatian dictionary has not been active for the past eight years. Maintainer of the current hunspell-hr dictionary has said that person behind the croatian dictionary extension has not responded for several years. https://addons.mozilla.org/en-US/firefox/addon/croatian-dictionary/ https://github.com/akoncic/mozillacroatiandictionary

What are your suggestions how to handel the situation? There is already a fork of the extension that is used as a pull request but has not been merged for years. https://github.com/krunose/mozillacroatiandictionary

Thank you for your understanding.

Have a wonderful rest of the day.

My spell check generally doesn't work, but occasionally comes back to life, I have tried the about config, and change value to 2, I have tried uploading dictionary, and making sure check as I type is ticked, but the setting on config seems to keep reverting to 1, and I'm sure if I have successfully uploaded a dictionary, I clicked on language pack, Ironically while I'm typing this, my spell check is actively involved.

Firefox is screwing my display with a screen logging warning message. Removal instructions are 100% useless.

This is so annoying. I’m sure its simples if you’re a techhie, but for muppets its hopeless, I’m desperate for a solution as i cant use Firefox now

Здравствуйте. Я установил сертификаты по инструкции, которая лежит на s.sber.ru/70VQ2B . После этого в мозилле не прогружается полностью окно входа на online.sberbank.ru, не видно содержимого фреймов (сейчас попробую сделать скриншот). В Microsoft Edge работа нормальная. Удаление сертификатов, перезапуск браузера и компьютера не помогли. На других компьютерах ещё не проверял. Посоветуйте, пожалуйста, что можно сделать. Windows 10, Firefox 153.0.3 (64-разрядный).

Does any of the mods know when the VPN for android will be available in the rollout regions ? I tried to connect and the toggle is now greyed out showing connecting..... Thank you

I paid for an annual subscription of Mozilla's VPN on 9/8/26. However, when I try to run the VPN, it is telling me I have to wait for the monthly trial (which I had previously to reset). My invoice is 98Z6LFXQ-0001. Also, when I printed a receipt of my purchase, I noticed my zip code is incorrect. My zip code is 11224 (not 11229). I saw that it could possibly take up to four days for my purchase to be reflected, but I wanted to get ahead of this potential problem ASAP. Thank you!

Since the last update 155.01 I can't use Firefox as it freezes and hangs after 3 - 10 seconds. On Windows 10 , 64 bit. There seems a bug with the last update for Windows 10 users

Crash report: https://crash-stats.mozilla.org/report/index/c0455e29-69e9-4030-8b03-fdf430260909

Not sure the crash report is related to the issue.

The same issue happens to all of my 3 Windows 10 PCs since the update from today.

I have uninstalled Firefox and downloaded again, but same issue happens again.

I cleared the cache also but to no avail

How can I use Firefox again?

Hi!

We have a intranet site that works in Edge and Chrome without issues with the site added to "internet options". But for some reason we are getting 401 Unauthorized when trying to access it from Firefox. I have tried adding the urls to: network.automatic-ntlm-auth.trusted-uris network.automatic-ntlm-auth.allow-proxies: true network.automatic-ntlm-auth.allow-non-fqdn: true network.auth.force-generic-ntlm: false network.auth.force-generic-ntlm-v1: false

Ingocnito mode , same error. I have tried disabling all plugins. Disabled DNS over HTTPS.

I get messages, questions and info from Firefox in Dutch. My language preferences in setting is English UK across the board. Browser, preferred, fall back and web site language. It works most of the time, apart from with Firefox. What can I do to make Firefox talk English to me?

This is a followup to a previous post. I pinned a tab in firefox, and later deleted the webpage that was pinnned. I do not see a way to edit the pin, so I deleted it and created a new one with the new, updated webpage. I use the sync feature to keep all of my browser settings the same across three computers. I have tried multiple approaches to correct the problem. 1. turned off the sync and manually unpinned the tab, cleared the cache and browser history, checked to be sure I do not have the option to reload previous tabs turned on, booted in the mode that does not load any plugins, rebooted the computers 2. with sync turned off, after all of those steps, I opened the new page and pinned it on each computer. when I close the browser and reopen it on any computer, the original pinned tab returns. Turning the sync back on or re-enabling the option to sync tabs and history have no effect.

Is there a way, even if it´s within the configuration files, to change that pinned tab or block the old one from opening? Note that the website for the old and the new pinned tab is the same. the difference is the page itself. the old tab was [website].administration-landing. the new page is [website].admin-lp.

The is no reason why the old page, which no longer exists, continues to be pinned in the browser, but I can´t get rid of it.

Please help. Thanks.

I tried updating Firefox or testing for the crash in Troubleshoot Mode, but it keeps crashing every minutes or so. Here is the report ID bp-67065b07-74d6-417e-b7de-caf500260906

I'm on FF 154.0. The power went out here and when it came back and I booted the desktop computer something had changed in FF.

I used to see the active tab as green in the tab bar and yellow for the rest, but now they're all gray until I mouse over the bar and only then does it turn green/yellow.

I struggled with this for many hours trying many //active tab color// solutions I found in searches but nothing got it back to my old behavior.

So as a last resort I tried adding the Firefox Color extension, but when I click Add to Firefox it just turns into a throbber that never changes so it doesn't install. I'm stuck!

Frustrated!!

Seemingly any program that has links that when clicked there, redirect and open a new tab in your browser just, do nothing now that I've swapped to Firefox? No indication or response on Firefox, it just acts like nothing happened. I don't even know why something this simple would break, let alone what WOULD break it.

I installed a Mozilla/FF GMail Notifier App. I tho't that I removed it as I no longer needed it. It still Notifies me; annoying. But it's not in my Extension List to Remove again if need be??? How can a hidden/invisible App be still operating, that is supposed to be Removed?

Since Mozilla/FF has no option to Delete a Question, I found the answer to the above posted. MY error: It was a Google Linked App, not the one I Removed which did indeed become Removed. Sigh!

There is seriously something wrong with the way Firefox operates. There is nothing wrong with the following site so why am I seeing this message?

Be careful. Something doesn’t look right.

Firefox spotted a potentially serious security issue with news.sky.com. Someone pretending to be the site could try to steal things like credit card info, passwords, or emails.

news.sky.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site. Advanced What makes the site look dangerous?

The site is set up to allow only secure connections, but there’s a problem with the site’s certificate. It’s possible that a bad actor is trying to impersonate the site. Sites use certificates issued by a certificate authority to prove they’re really who they say they are. Firefox doesn’t trust this site because its certificate isn’t valid for news.sky.com. The certificate is only valid for: . What can you do about it?
