Firefox Support Forum

For some reason the developer tool on Firefox is just completely blank when I open it. Nothing will load and I can't even close out of it. Any ideas on how to fix this?

On firefox 126.0 (64-bit) the option for spelling check is enabled, but will not appear on the context menu box when right clicked. This happens for the desktop sites of Facebook and Instagram.

On Mac OS 14.4 Firefox hangs on launch and crashes, requiring "Force Quit" when I try to Refresh or Troubleshoot. Uninstalled and reinstalled multiple times, and restarted computer several times. Have spent several hours trying multiple community suggestions to now avail.

I am not a programmer, but am able to follow instructions. I clearly need someone to hold my hand and walk me through the solution. (I even checked out the Kaspersky suggestion, but cannot install it because Firefox cannot connect to the Internet.)

I have downloaded and saved "Raw Data.docx" and "Application Basics tex.docx" from one of the crash reports.

P.S. On this question form Firefox guessed that my operation system was Mac OS x 10_15_7, but it is 14.4

We are receiving the following error when we change the security.OCSP.enabled to "1" and security.OCSP.require to "true":

(Invalid OCSP signing certificate in OCSP response(Error code: sec_error_ocsp_invalid_signing_cert)

We are in an airgapped environment and have our own OCSP responder we are attempting to get Firefox to work with. What configuration does Firefox need in order to solve this error?

Hi there, Can anyone help me please. Ive been using Firefox forever and yesterday I signed into a Gmail account to send an email to someone, I typed in who it was to, then subject and then when I went to type into the body of text, the keyboard wont work.

I thought there was an issue with the keyboard but I then I tried to type in issues on firfox and loads of text is missing, I basically cant use firefox at the moment as Im only viewing half the info.

Ive been sent a credit not from someone and this is what its viewing like.

I didnt change anything that Im aware of

Thanks and fingers crossed in anticipation. Andrea

I don’t understand what Firefox is doing. For example, I used to start typing the first few letters of “weather.com”, which I visit pretty much daily, and it would auto fill “weather.com”. Now it auto fills every time with http://www.weatherbase.com/. I don’t know where that came from. Similarly, I used to type the first few letters of “duckduckgo.com” and it would bring up “duckduckgo.com”. Now it brings up a magnifying glass below the url with “Search with duckduckgo”. I am thinking it might be best if I can start over, i.e. clear out any information it’s saved about where it thinks I want to go, and start remembering the sites I am entering now.

Here is my crash report. https://crash-stats.mozilla.org/report/index/ac6dbca9-a495-4b78-a72f-8102b0240528#tab-details

Based on https://gitlab.gnome.org/GNOME/glib/-/issues/2833, I gather that this crash happens when you have some malformed xdg-mime data. I'm trying to figure out what data that is and where it's stored so I can fix it.

The crash report doesn't show me the arguments, so I can't tell what mime type it's trying to load. Maybe it's not available due to the way the library is built, or maybe it's not available due to the crash report hiding potentially private data. Or both. Can anyone tell me how to see what mime type it's looking up? Or do you know what mime type it would be looking up when saving a PDF? `xdg-mime query default application/pdf` works fine so it's not just looking for a handler, there must be some sort of weird "MIME type" for "file browser" that it's trying to use.

I'm unable to load this specific website "https://doy2mn9upadnk.cloudfront.net/" just on Firefox browser, i keep getting same error "PR_CONNECT_RESET_ERROR" yet it loads perfectly fine in Chrome. I don't use any vpn/proxy

I often run into issues with PDFs in Firefox Linux. They either appear totally blank (typically after suspend/restore), or they appear with the desktop background showing through (as in the attached screenshot).

Hard refreshing the page doesn't change anything, opening a new tab and opening the PDF again doesn't change anything, opening a new window and loading the PDF doesn't change anything.

The screenshot is with this PDF: https://www.sgsw.ch/home/strom/_jcr_content/Par/sgsw_accordion_list_1838160259/AccordionListPar/sgsw_accordion_12353/AccordionPar/sgsw_downloadlist/DownloadListPar/sgsw_download_1049323524.ocFile/2023-08-31%20Mitteilung%20Elcom%20Erh%C3%B6hung%20Elektrizit%C3%A4tspreise%20f%C3%BCr%20das%20Jahr%202024.pdf

It renders correctly in Chromium.

Hello Mozilla community,

I'm encountering a perplexing issue with Mozilla Firefox that I hope someone here can shed some light on. Whenever I set Mozilla Firefox as my default browser, I experience difficulties accessing my website. The site continuously buffers but never fully loads, leaving me unable to view its content.

However, when I switch to a different browser as my default, such as Google Chrome or Microsoft Edge, the website loads without any issues moreover my website is related to Picoworker which runs smoothly on other browsers (Screenshot is also attached). This leads me to believe that the problem might be specific to Mozilla Firefox.

I've tried troubleshooting by clearing the browser cache, disabling extensions, and even reinstalling Firefox, but the problem persists. I've also checked for any errors in the browser console, but nothing seems out of the ordinary.

Could there be any compatibility issues between my website and Mozilla Firefox that are causing this problem? Or is there something else I should investigate to resolve this issue?

Any insights or suggestions would be greatly appreciated. Thank you in advance for your assistance!

Hi all!

A while back I downgraded my Firefox version to some old version to be able to access a FortiGate 310B. However when I upgraded back and started using the latest version my search completion stopped working, but my search completion is turned on. It shows things I've already searched for, but it's not fetching new completions. I lived with this for a while since I couldn't be bothered to fix it, but I recently moved to linux, and copied all my data, I did this by just copying the profile folder and moved into into a new profile I created on linux. It worked, my bookmark, history, passwords etc are saved, but still no completion. I tried creating a new profile and the search completion worked perfectly fine. Do you guys have any tips or things I could try? Or do I just give up and move to a new profile, since this one is presumably corrupt?

Any help is appreciated, cheers :)

After the last upgrade Firefox has a strange ~6 pixel wide dark border. How can I eliminate that border?

Thanks. :-)

So I have an issue where I am unable to reorder or detach tabs after having detached one tab. When I start Firefox I am able to reorder my tabs as much as I want, but once I detach one tab both functionalities do not work anymore.

- Firefox version 126.0 on Kubuntu 24.04 - After restarting Firefox I am able to do it again once - After rebooting I am also able to do it again once - The same issue in private window - I have refreshed Firefox through Help -> More troubleshooting information - Disabled all my add-ons - Tried it in Troubleshoot mode

I cannot seem to find a real answer online. Does somebody here have a solution for me :-)?

Zainstalowałem sobie przeglądarkę Firefox. Importowałem z Google Chrome dane, w tym historię. Historia stamtąd była z dobrych kilku miesięcy.

Gdy wchodzę w historię, z opcji mogę widzieć historię maksymalnie z ostatnich 7 dni, miałem opcje oglądania historii z ostatniego miesiąca, co było po zainstalowaniu przeglądarki. A chciałbym mieć opcję obejrzenia z co najmniej pół roku.

W poniższym poradniku można widzieć historię z dłużej niż pół roku i właśnie tak chciałbym mieć u siebie.

https://x.com/ (Formaly Twitter) Firefox’s Enhanced Tracking Protection (Strict Mode) is known to cause issues on x.com

Not only me: https://www.reddit.com/r/firefox/comments/1ctx1bm/twitter_not_working_on_private_browsing/ https://connect.mozilla.org/t5/discussions/firefox-s-enhanced-tracking-protection-strict-mode-is-known-to/td-p/57432 https://lemmy.world/post/15496431

https://news.ycombinator.com/item?id=40386418 Dunno if entirely accurate but regarding the Firefox error: “Twitter switched their top level domain to X, but didn't change any of their other domains, so they're still pulling assets from Twimg. Which makes Firefox (correctly) block the page if you have Tracking Protect enabled because it sees X trying to involve 3rd parties.“ Slow clap.

Greetings,

I have happily used Firefox for a very very long time and all has been well until the last month or so.

I have a brand new laptop with Windows 11 Pro and Firefox 126.

Each time I open the machine to begin a new day and open Firefox, all my tabs are gone from the previous session; this is not good for my research, studies, and business activities. I have read a lot about this issue online and (1) find that under Settings, History, there is no "restore previous session" option; and (2) I have several times already cleared the "sessionstore" folder and copied the files for later reuse.

Further, "Open previous windows and tabs" is checked off; always has been. I have checked other relevant settings and they all seem fine; but to no avail.

What would you suggest?

Thanks, Donald Sanders

I use version 115.11.0esr (32-bit). I need help with the color of open tabs. How do open tabs can be all in one color and that is black or dark gray? I don't want all open tabs to be bright because it stitches me in the eye. Active tab can be any color but for all other open tabs I want them to be in the same dark color - black or dark gray. Is this possible and how can this be achieved? Thanks very much.
