Diễn đàn hỗ trợ Firefox

For the past couple of months I have been getting the message www.bbc.com. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR when loading pages on www.bbc.com website. I have done a search on the internet and it seems this is a common problem with Firefox and does not affect othere browesers. I have done what was advice given online but it does not solve the problem. It is getting so bad I may have to start using one of the other browsers even though I prefare Firefox.

Support,

The USPS website does not work properly with Firefox!! The Home page loads okay but there are multiple other issues with links not working. For instance all of the links under Quick Tools do not work except this one: https://www.usps.com/manage/po-boxes.htm. Other things don't work either.

Everything works fine that I tried with Google Chrome though! Please address soon.

Thanks

On a couple of sites (e.g. Petapixel) when I click "Load Comments", nothing happens. I suspect this may be because Firefox security is preventing comments from loading because of site tracking or other security issues. Is this the cause?

Firefox will not allow my to post comments on Yahoo. I have no issues with Chrome or Safari. I get the following error message: Your comment failed to publish. Retry

TL;DR : Disqus comments used to work while using privacy Strict mode now it doesn't.

After years of it working out of the get-go while using Strict mode up till recently (about a year ago this was really low on my priority list) refused to work I though it was my Ad blocker was causing issues but after setting it in the filters to allow and even after turning it off still no dice.

Removed all add-ons tried again still Disqus comment section refused to load in the websites I regularly visit. So after giving up, I just look around in the browser setting to see if there is anything that may cause conflict with certain scripts from running.

Hi everyone,

I'm used to typing one or two letters into the address bar and then the down arrow to access the same handful of websites every day. A few weeks ago, Firefox started randomly moving these around so that the same letters that have always made it open the same URL now opens a different URL and I have to actually search the suggestions. How can this annoying behaviour be fixed?

(a few months ago, the address bar wouldn't delete entries, but this problem vanished as mysteriously as it appeared)

FF version 122.0.1 (64-bit), Windows 10

Hello there, Iam facing a problem with changing Firefox homepage background. I tried every solution, tutorial, oldposts etc. nothing seems to work, here is what I tried. -1- The chrome folder is in the right folder. -2- the naming of both CSS files userChrome, userContent. -3- enabled CSS files at startup -4- search for both CSS files in the browser toolbox for some reason I cannot find both CSS files, even though they are in the chrome directory. Also, I have 2 chrome folders one of them is located here. "AppData\Roaming\Mozilla\Firefox\Profiles\shaf5qn0.default-release\storage\permanent\chrome" the other one I created myself which is here "AppData\Roaming\Mozilla\Firefox\Profiles\shaf5qn0.default-release\chrome" I tried to delete the first one but I cant, I get an error that this file is being used even though I did close Firefox. What I am missing here?

My system broke during an update. Now I want to import my old Firefox userdata, but everytime I try to use the old data firefox just forces the creation of a new profile?

Is it completely impossible to recover data not created with the same firefox version?

When I try to access my payment preferences page on xfinity.com, the page goes blank and it appears that it is being blocked. I can't figure out how to unblock it. I had to use Microsoft Edge to access the page to change my information. Can you please assist?

I am no longer able to add attachments to gmail or upload images or attachments to websites. When I click on the attachment icon or upload button, my finder window does not open. However, it works in other browsers. How can I fix this?

I have Yahoo as my home page and usually search from it starting out. I noticed, however, after the last update or two in the last week that when I hit search, it opens the search results in a new tab. It didn't use to do this, but I can't find any Firefox option to make the searches stay in the existing tab. Can anyone help with this? I don't think it's Yahoo's settings, because I'm not signed into it. It seems like the Firefox update created this new behavior.

Today when I close many tabs using control w firefox seems to randomly jump around when choosing which next tab to close

I wish to have firefox always close the adjacent tab to the tab I just closed

This should be the default behavior ... I do not see any setting for this ... is there an addon to do this ?

I am using the latest firefox on ubuntu

• • • UPDATE*** below answer for setting `browser.tabs.selectOwnerOnClose` has no impact on this

Why can't Firefox copy text to the clipboard anymore? It won't copy text from a web page, from a URL, or even from about:support "Copy text to clipboard"!!! I'm using version 1.22 64 bit on windows 11. I've reinstalled Firefox but it doesn't make a difference. I've tried "Troubleshoot Mode" and it's still broken!!!

I can paste into Firefox but something has broken copy!

How to reproduce the bug: Jump to the address bar, and then press shift, ctrol, alt or windows_start, you can see the address getting deleted. You can also see it in Google Sheets and Microsoft Excel Online, it just deletes the cell, or a selection of multiple cells. --Interestingly on Google Docs it doesn't delete but just move the cursor to the first character when a string is selected.

 It happens only once per mouse click, or focus change

What I expect: Shift, Control or any mod key should not delete content or move a cursor

Thanks!

I'm not sure how this happened, but one of my firefox web pages keeps zooming in only on one website and the zoom refuses to reset no matter what I do.

For reference this is wikipedia. Every time I load a wikipedia page it loads zoomed in to 210%, which I will then have to reset to 100% in order to read the page properly. If I for some reason click on a link on the wikipedia page that goes to another wikipedia page, the zoom will reset again to 210%, which I will then need to reset once again. This happens also whenever I switch from the wikipedia tab to another tab and then switch back again. I do have an addon that changes wikipedia slightly (the Wikipedia Vector Skin addon) but disabling this addon doesn't fix the issue.

I went into about:config several times already and changed different settings to try and make it stop, but nothing so far has worked. I've tried resetting layout.css.devPixelsPerPx to 1.0 and back again to -1.0 and it makes no difference. I also tried changing browser.zoom.full to false and it keeps happening. Changing browser.zoom.siteSpecific to false does fix the issue, however it also resets the zoom I have on other websites that I want to keep, so it's not an ideal fix. I also cleared all my cache and cookies and it changed nothing.

Does anyone have any idea on why this keeps happening only with wikipedia, and how I can get this to stop happening? I assume there must be some internal setting that would need to be reset in order to fix this, but I don't know how to do it or where I would even go.
