Firefox Support Forum

I have a Netgear Readynas attached storage device. I am unable to connect to this device using Firefox. I encounter : Error code: SSL_ERROR_UNSUPPORTED_VERSION

It is not an dangerous site, it is my network storage device.

Is there a way to configure Firefox to connect to this device? Thanks for any help

Normally there is no difficulty searching a pdf with a pdf reader. How does one do it in Firefox?

Note that ctrl+shift+f and ctrl+f do not work.

Hello,

I have autofills and login savings disabled, but browser still seems to be saving form data including usernames. How do I disable browser saving any form inputs altogether?

Hi,

I would like to change the light grey hover color on menus (e.g. yellow), see attachments, probably using userchrome.css.

Does anyone know the correct code to do this please?

Thanks in advance.

I need to turn off my Delete cookies and site data when Firefox is closed setting.I have wrongly turn on this setting i need to turn off this setting.please help me to change it.

My Firefox has suddenly stopped working when websites have menus you need to scroll through on the right side. Example: websites where you are drilling down through filter options, or in Ancestry where you will typically open a record in the hints screen and scroll down through the detail. The right scroll navigation causes the whole page to scroll up and down; there's no way to navigate down in the sub-display. I have run FF in safe mode, and done a scorched-earth uninstall/reinstall and the problem persists even with no plug-ins restored. This is on a machine running Windows 11. The machine crashed right before this became a problem. Sites work in Edge without issue.

I used to be able to get on Amazon with no problems using Firefox. Lately, the website is all chopped up. Blue words with underlining appears on the pages. I can view Amazon just fine under Safari.

Hello,

I have been unable to watch Netflix or any "other" video content using the Firefox browser for the past few weeks. I've been pulling my hair out while working through the help articles, alongside bouts of furious googling - all to no avail.

On Netflix I am getting error code F7701- 1003. Netflix is telling me to use the latest version of Firefox, but I have been checking for new updates almost every day since I noticed this issue. My current version is 100.0 (64-bit) On other website I'm getting the error message "No compatible source was found for this media."

I have followed all of the fixes listed on the following articles, but so far have not been able to fix my problem: Fix common audio and video issues Fix video and audio problems on Firefox for Windows N editions

If there is anything I haven't tried yet, please let me know.

I was using Ctrl+K on some websites to do things like site-specific search, task bars, and so forth, but recently Firefox started capturing it for focusing on the search/address bar (https://support.mozilla.org/en-US/kb/keyboard-shortcuts-perform-firefox-tasks-quickly#w_search).

Is there a way to unbind `Ctrl+K` in Firefox?

The background on the homepage link shortcut boxes keeps reverting to black and text underneath to white on my off-white background when a new version loads. I've used Colors to customize the look of my firefox but can't find any control for that. Once a new version kept the boxes white and the text black but now it's back to black again. Where is the control to fix this?

I had jira as my default search engine (https://jira.<mydomain>.com). This continues to work on my existing profile. But i am unable to add it on a new profile, I get an error "Firefox could not install the search engine from: https://jira.<mydomain>.com/osd.jsp"

So, i tried copying the existing profile folder and using that folder for the new profile, but firefox removes the jira search engine and gives me a warning saying that the default search engine was changed to Google (screenshot attached)

Is there a way to get this added via a hack of some kind? I wanted separate profiles so that I keep my project profiles separated - bookmarks, cookies, scripts etc.,

I use the recent activity page as a homepage with the icons of the websites that I most frequently use. but i can't figure how to adjust/pick the icons (websites) that I want to appear on this page. Something is picking them for me. And when I delete an icon another one pops in place but is generally a website I rarely use. How can I choose the icons (websites) that I want to appear on this page?

I haven't used my microphone in Firefox in years. I tried today, logged into Google Voice, which tells me it can't access the microphone. I set permissions in Firefox's settings. I turned up all the mic settings in alsamixer. I tried https://mdn.github.io/web-dictaphone/ , recommended in another thread here, and it doesn't record either. I can use the microphone outside X, with sox's rec. I also can't record a new greeting in Google Voice.

Firefox 100.0.2 , Linux, Slackware 64-bit, all packages updated this morning.

Just now, I tried to use "Email Link..." under the File Menu and got a pop-up asking me to "Choose an application to open the mailto link." I have seen this before, several times, and usually fix it by going to Tools > Settings, under General > Applications, select "mailto" under Content Type, then select Gmail from the drop-down menu.

This time, however, Gmail is not presented as an option, in this pop-up. Clicking "Choose..." just opens up a Windows Explorer file-picker window.

I tried to fix this in Tools > Settings, under General > Applications. There, "mailto" just shows "Use other..." and if I click that, the "Select Helper Application" pop-up window is basically blank, with a message at the bottom saying "No applications were found for this file type."

I refreshed Firefox but it did not solve the problem.

I have tried to attached images but they will not upload.

I am running v100.0.1 (64-bit) on Windows 11

In order to more convenient drag-and-drop interface, I need a fixed fixed space in nav-bar like Edge. For now we can add a flexible space on it. But it's flexible and it will disappear when I use a side window. And I can't drag over titlebar-buttonbox-container Please help me. Thanks!

When i have like 50+ tabs pinned then firefox breaks and we cannot scroll tabs anymore. Of course closing tabs doesn;t work with Ctrl+W, but then we need some different shortcut for closing pinned tabs (like for example Ctrl + Shift + W) or just you fixing this bug ;) I attach 2 screenshots that show what happens with Firefox when having too many tabs pinned. I can't navigate through tabs anymore.

Having any google related webpage open for more than a couple of minutes causes it to disconnect (gmail, calendar). This results in no connectivity to any Google services. Opening new tabs will refuse to load even Google.com. The only fix is to completely close out of Firefox and relaunch. But having gmail open for a few minutes will result in it disconnecting again.

The issue persists in 'troubleshooting mode' as well as after doing a refresh. I have experienced this now for the past couple of weeks on my Windows 10 work laptop. I have also seen this on 2 different Linux machines in the past few days. I had attempted to disable http3 and telemetry settings from an older post I had found, but no luck. Not sure what else to try at this point.

In KDE 5.24.4, Linux. I started to have some issues with "Open containing folder" probably because I installed many Gnome apps which may cause bad configurations in my system.

I suspect this cause this issue even though I don't really have gnome file manager:

https://polywogsys.livejournal.com/309405.html "Gnome based file managers, Nemo/Caja/Nautilus provide the entry org.freedesktop.FileManager1. So it doesn't matter what you set as your default application for the filemanager mimetype - as per the freedesktop.org standard, firefox will always select a filemanager based on dbus (if it's there)"

But because the mimetype points to "dolphin", I dont really have other explanation either: $ xdg-mime query default inode/directory org.kde.dolphin.desktop

UAC notification pops up every time I try to open Firefox since last update on 5/5/22. I've deselected all options that run the program as an administrator, but it still shows up every time. I've checked that no admin is selected in both the shortcut I use and in the program itself. Any suggestions?

The browser takes extremely long time to start-up. Task manager shows that it's trying to pull some 200mbs of data at the rate of 0.5mb\s or less. RAM is fine. HDD is old, but recently defragmented and, outside of <this> particular issue - it's not a problem. System is dusty, but system is system. For some reason virtually any other program launches more or less just fine. A particularly heavy game can pull gigabytes of data in about the same time that Firefox is bottlenecked to kilobyte speed.

It's not a conflict of start-ups, I have only the driver necessities in there. it's not a windows start-up issue, the browser can take as much time even a minute after windows is loaded. It's not a (anti)virus. Because I don't use either. It's not some 15 year old Celeron trying to handle W10, FX8320 should be able to handle opening a web browser. It's not a ton of extensions, and it's not even Firefox accounting, it happened before I registered. From extensions it's only ublock origin and VPN.

My personal three guesses are:

-More than 3-5 tabs on average, but, last I checked, the tabs aren't loaded upon start-up. And power users have sessions of dozens of tabs. -100-200 bookmarks. Again, not sure how hard is it to read a text data, unless it also has to load some thumbnails or icons or whatever. -Software aging.(Latest stable firefox, updates are on, and it has been running far less than this 4 year old system)

Reinstalling the system isn't a solution. Nor is reinstalling Firefox. Nor is dumping bookmarks, because otherwise why bookmark them. I'd just like to know why is Firefox limited to kilobyte speed of initial page loading. It can't be a damaged HDD cluster, otherwise I'd feel it outside of start-up.

With my limited knowledge of PC - it's usually a random read issue. Because like every memory benchmarks(HDD and RAM) can show hysterical speeds when loading\copying some 50gigs of a single file, if it's a few hundreds of thousands of small files - it becomes random and tanks. But what I don't understand why does Firefox have THAT much clutter? Is it really the bookmarks?
