When I try to screenshot (Windows+Shift+S) and paste the screenshot into Google Translate, I get the error message:

Unable to paste from clipboard right now. Try copying the image again.

This functionality works in every other browser I've tried (Chrome, Edge, Brave, Opera GX), so it's not a Google problem, I don't think.

As I understand, `autoconfig.js` (with `firefox.cfg`) can be used to have JavaScript run during startup to control Firefox's UI elements.

I have set up `autoconfig.js` in my `/usr/lib/firefox-developer-edition/defaults/pref` folder (I'm on EndeavourOS Linux). As instructed here, I've already put the two required files, `autoconfig.js` and `firefox.cfg` in their correct folders (`/usr/lib/firefox-developer-edition/defaults/pref` and `/usr/lib/firefox-developer-edition` in my machine).

The file `firefox.cfg` contains the following code:

 //
 (() => {
   var tabbar = document.getElementById("TabsToolbar");
 })();

However, every time I run Firefox, this message will appear:

 "Failed to read the configuration file. Please contact your system administrator."

If I empty out the `firefox.cfg` file, Firefox will run normally without showing the error message. It will also run normally if I just have something like this in the file:

 //
 (() => {
   var testVar = "";
 })();

I don't understand why the JavaScript code can't access the Firefox UI elements through `document` or `window.document`. If `autoconfig.js` isn't build for that, what should I use to change my browser's UI elements through JavaScript?

Thank you.

Hi all, In the past I was using Chrome and I have decided to move back to Firefox because I didn't like certain trends of that browser...now...the thing is...I like to use Yandex, but in Chrome -until a certain point- I was able to alter its settings to force default English language for it.

Firefox seems to have Yandex set as default...you cannot alter it and you cannot delete any of the default engines (i.e., because if it is loaded, you seem unable to try add it as custom search engine with your chosen parameters), but seems that the Mozilla developers had the brilliant idea to add it with the default settings...which is in Russian...

...and you look into Extensions and all the people writing extensions seemed to have the same idea...

Now...fine that Yandex is mostly for Russian people, but why English-speaking users to be forced with the default search in Russian and being completely denied any possibility to force the English language on Yandex (as it is fully possible if you were able to tweak the search parameters...but Firefox isn't allowing to do, because the only thing we have is a dumbed down interface with a list of search engines!)...

...alternatively...why not allow to force our favored language parameters to ALL search engines by default?

( That would mean that one could have Google, Bing or Yandex in a different language of our choice....but that change would need to be implemented on developer side...)

Recently I had to refresh Windows 11 on my Dell desktop. It defaulted to McAfee antivirus. I uninstalled McAfee and reinstalled Norton 360 which I had before. I reinstalled Firefox. I have version 123.0.1. I imported my FF bookmarks after exporting them from another computer. Now, FF remembers my IDs but not my passwords. When I log in to a website, FF offers to save my password and when I click yes it pops up a bubble saying "Password saved!" However, next time I go to that website, although it remembers my ID, it does not recall my (supposedly saved) password. In this support site, I see most users with this problem say FF will not remember either their IDs or passwords, whereas FF remembers my IDs, so my problem may be different. In FF help, I see that another password manager could be keeping FF from saving passwords. To the best of my knowledge I have never used another password manager. What is keeping FF from saving my passwords, while remembering my IDs? Is there a Windows Registry setting or a FF About:Configuration setting I need to change? Is re-installing FF a last ditch option?

My Firefox has gotten so buggy lately I can't use it. I'm writing from Edge. THere are numerous issues. The sign in process got messed up a couple months ago. IT asks for email address, then doesn't provide password screen option, takes forever to send email, and then sometimes repeats itself. Tabs crash and clicks fail to work randomly. Out of desperation I reset my Firefox password and that seemed to help temporarily, but not enough. So what's happened and how to fix??? Thanks.

As of today, I am unable to scroll with my mouse in google sheets. The scroll bar on the right disappears and I'm taken to the bottom of the spreadsheet and can't scroll back up. I have to use CTRL+Home and then the arrow keys to go down the rows. This appears to be only on Firefox. I tried a different browser and it worked fine.

For the past week, when I sign into Facebook, the news feed is constantly refreshing itself. Once in a while the first post will stay, but the remainder of the news feed keeps refreshing. It is impossible to read anything as posts flash on and off, mostly off. The news feed is the only thing that is affected, visiting pages for likes and groups load and display properly, as do the games I play. The same occurs if in the private window mode. This does not happen if in the Chrome browser. What can be done to correct this situation?

Whenever I log on to my bank's web site, I'm sent an audible signal that invites me to start a chat session with a bank agent. The problem is that the audible alert is so loud that it startles me. This is very annoying. I called the bank's help line and was told there was no way they could adjust the sound volume. I would like to know if it's possible for Firefox to decrease the volume for that web site.

Dear Technical Support,

I'd like to report a problem which affects the rendering of websites in Firefox with a HiDPI monitor.

I'm having issues with the text and graphics of web pages, that are often mismatched or misaligned, with text being too large compared to graphical elements. See the enclosed pictures for an example; as you can see, this happens also on your website. Also, I've noted that pages (and plugins) appear to be "shrinked" as opposed to when viewed on Chrome, where they are shown to their true size.

Setting ui.textScaleFactor=100 and tweaking with layout.css.devPixelsPerPx did not change much. I must admit that I find this behavior quite strange, since HiDPI monitors have been around for more than a decade, and especially considering that this did not impact my experience with Firefox on Windows, using the same monitor and machine.

I hope to find an effective solution to this problem and look forward to your reply. Please let me know if I can be of any help in this matter.

Best regards, Federico

ONE EXAMPLE - This morning I wanted to sign into my Navy Federal Credit Union account. I got the following error message:

You don't have permission to access "http://signon.navyfederal.org/siteminderagent/forms/mfa.fcc" on this server.

Reference #18.7efdd17.1710862426.19b449b3

I called the Credit Union. NO PROBLEMS at their end. I was asked which browser. I was told that Firefox is frequently the problem! I changed to Google Chrome and had NO trouble signing in.

I have had this problem previously with a few other websites.

ANY WAY for ME to fix the problem since I FAR prefer Firefox?

Thanks,Arthur

I have a problem with firefox notifications for twitter. They appear in a separate window and when I click somewhere, they disappear as if they were in the foreground and hiding. The second thing is clogging and then I get a massive series of delayed notifications. help

while reading an MSNBC or Fox News article (for example) from flipboard, suppose there is a video at the top of the article. But I don't want to watch that video... I just want to read the article that appears below it. So I start to scroll down, reading the article, and when the video scrolls off the screen at the top, a picture-in-picture with that video appears at the right side of the article, (sometimes blocking part of the article). If I had wanted to see the video, I would have watched the video! STOP these blasted picture-in-picure pop-ups.

Every time I look for help online, all I see is how to enable/disable the PIP controls, and no help on how to block PIPs themselves.

Sorry for the long post, but I don't know how else to describe the problem succinctly. Jerry (at wit's end)

For the last several months, I have been unable to get audio input from any device working on Firefox. The mic inputs work in all other apps and browsers, are appropriately permissioned on Windows 11, and appear in the Firefox permission windows. No actual audio is received by the website.

I have installed Firefox clean, rebooted countless times, tried the Beta and Dev channel releases, and disabled all extensions, to no avail. I have ensured that I am on the latest releases, have tried various devices, run virus scans. I have included images of the Windows sound settings showing working Mic levels, Firefox showing the device in permissions, etc.

My sound drivers are up to date, and mics work in all other browsers and apps. This is limited exclusively to Firefox.

Macos sonoma m1 - firefox is default browser, duck duck go is default search engine

When doing a search directly from searchlight options, firefox uses google search instead of the duck duck go default.

All other searches from within firefox uses the default correctly.

AFTER RESETTING MY MACBOOK PRO I DISCOVERED THAT MY ALL MY PASSWORDS AND EMAIL SAVED TO MY ACCOUNT HAVE BEEN REMOVED/DELETED. PLEASE HELP WITH THIS PROBLEM AS SOON AS POSSIBLE. THANK YOU.

Hello, I use Firefox as my only browser and I use the shortcuts because they're really helpful. But every time that I lunch Firefox all the pages in the shortcuts "call" their websites, I see it from pihole and all the requests are made every first lunch of Firefox. Probably it's something related to the cache and to give better perfomances in case I wanna select one of those shortcuts, but I don't want that all of them make a "call" to their respective websites. I think it's something related to privacy and freedom about what I want to do with mt browser. Is there an option to block those connections? In case there isn't an option is possible to implement it? Thank you so much

I have Firefox on Windows, Linux, and Android. Anytime I use Firefox on a desktop, it sends me to Tornado Alley in Kansas. However, I am not in Kansas, and I don't have dog named Toto either. I am in the Detroit area. If I use other browsers, I don't have this problem. It only happens on desktop computers. On my cell phone it shows the correct location. I have already done the simple troubleshooting measure (for a year now: clearing cache, uninstall, reinstall, etc...) and NOTHING removes me from this Tornado Alley, Kansas location on the Firefox browser. If I use Chrome, Opera, Edge, etc... I don't get this problem. It must be something in the Firefox program.

Hi, I watch specific streaming live show on YouTube every week. Unfortunately, I always have to play it in non-Firefox browser, because the video freezes every couple minutes, while audio track is still playing in the background. Based on the comments from the stream chat, other people have this issue too. Why? How to fix it? It is annoying. Internet connection is ok. Other browsers no issue.
