Diễn đàn hỗ trợ Firefox

I use Firefox as the browser for my email. Recently I have been unable to open or download pdf attachments (or any attachment) to emails. When I click on the attachment I get the message javascript:void(0).

I contacted the email company who said there was no problem at their end and that the problem was with Firefox and pop up blockers. I followed the advice in the attachment to unblock for my email account - but this did not solve the problem.

So I then tried Edge for my emails and I can open attachments in Edge.

So the problem is with Firefox.

Any advice please? Thanks

Hello,

I have had a few websites not work properly with Firefox and have needed to open my backup browser (Avast Secure Browser) to use those websites.

Right now it is FedEx that comes to mind again as I kept checking for tracking of packages shipped to me since receiving the tracking info. I queries consistently returned the error message "Unfortunately we are unable to retrieve your tracking results at this time. Please try again later."

Thinking maybe the website was having issues or maintenance (and forgetting I had the same issue with FedEx website the last time I tried tracking there in Firefox), I kept "trying again later".

Then I opened my Avast browser and pasted the same url there and, sure enough, received this report on the display:

Travel History Date or Time City & State Status Monday, April 18, 2022 9:47 PM SPARROWS POINT, MD Departed FedEx location Sunday, April 17, 2022 1:49 PM Shipment information sent to FedEx

I have tried disabling the extension NoScript as well as turning off the "Enhanced tracking protection" and allowing permissions for the FedEx site with no improvement.

I copied and pasted the RAW data as well as the text version from the "about:support" page to send you.

Any suggestions to fix this?

Thank you, Keith McNabb

I work on kubuntu 20.04 with plasma 5.18.8 desktop environment. I have a QtCurve-based custom application style, which I almost match with css for GTK apps. Firefox has to be an exception by itself! Not only that, but it changes my ability to customize its interface, from time to time and even changes access to such ability, on some updates.

My scrollbar customizations in userChrome.css and userContent.css do not work any more (other CSS changes still work, for menu/addressbar/tabbar/bookmarksbar orderint and tab styling). I had to resort to settings in user.js file, to get a 20px width scrollbar, suitable for my big screen, but... it gets very wide when I increase the focus, on some webpages and becomes very ugly! Furthermore, I cannot make sense of the proper use of "ui.themedScrollbar*" settings and the scrollbar and its slider result in the same color. These are my settings in user.js:

user_pref("widget.content.gtk-theme-override", "backwater"); user_pref("widget.non-native-theme.enabled", false); // Use GTK-3.0 gtk.css: set to false user_pref("toolkit.legacyUserProfileCustomizations.stylesheets", true); // Use userChrome.css & userContent.css: set to true user_pref("widget.gtk.alt-theme.scrollbar_active", true); user_pref("widget.non-native-theme.scrollbar.size.override", 20); // If nothing else works, fix scrollbar width to 20px user_pref("widget.non-native-theme.gtk.scrollbar.round-thumb", false); user_pref("widget.non-native-theme.gtk.scrollbar.thumb-size", 1.0); // originally 0.75 user_pref("widget.non-native-theme.gtk.scrollbar.allow-buttons", true); // it was true, anyway... user_pref("layout.css.cached-scrollbar-styles.enabled", false); user_pref("layout.css.color-mix.enabled", true); user_pref("widget.non-native-theme.scrollbar.style", 4); // wide scrollbar theme: set to 4 user_pref("ui.themedScrollbar", "#bad1f5"); user_pref("ui.themedScrollbarInactive", "#668cc4"); user_pref("ui.themedScrollbarThumb", "#e4e4e4"); user_pref("ui.themedScrollbarThumbHover", "#e4e4e4"); user_pref("ui.themedScrollbarThumbActive", "#668cc4"); user_pref("ui.themedScrollbarThumbInactive", "#bad1f5"); user_pref("browser.dom.window.dump.enabled", false); user_pref("extensions.ui.sitepermission.hidden", false); user_pref("fission.experiment.max-origins.qualified", true);

Either with the "ui.themedScrollbar*" settings or without them (and cleared from the prefs.js file), the scrollbar and its slider result in the same color, unless I (tryingly) click on some place on the scrollbar outside its slider; then I can see the slider, _only_ for the duration of the mouse-down event (which causes up or down page-hight scrolling).

The default, very thin scrollbar, as well as my modified wide scrollbar with invisible slider are both useless to me! I have even tried fx-autoconfig (https://github.com/MrOtherGuy/fx-autoconfig) to make the scrollbar CSS work, but no result. At this point, I am considering switching to another browser, despite the trust I have to mozilla, for my data and privacy.

Until recently, I resisted allowing updates for Firefox because of the announcements of changes to prevent access to some technical kinds of website which I use. These include the public websites of the Paris Observatory which include useul informational ftp pages with important text, data and software files.

  I did recently allow a Firefox update, and now I find that I am cut off from access to these ftp pages. 
  How can I re-enable access to ftp? If it can't be done in the new version of Firefox, how can I return to an older Firefox version that does allow such access?

my pc had friend so when i got a new one i lost all of my firefox data, how can i get all of it back so i was forced to start all over, i lost all my, bookmarks, tabs, history and saved passwords

When I use Firefox on my Mac, no matter what I have tried it keeps defaulting to the dreaded Bing Search Engine. I understand it has to do with Microsoft, but I don't use any of their products because I don't like them. In settings/search I can restore the default search engines & delete Bing, but it always reverts back to insisting on using Bing again. I have followed several threads about this issue without permanent resolution. Help??

When I start to type a reply to a Facebook post, the page scrolls down so that the line I am typing disappears one line below the bottom of the screen. I have to scroll down to see what I'm typing. Also, it jumps down the same way whenever I hit the backspace key to edit what I'm typing.

I discovered a previous (archived) post on this forum that suggested using "about.config" and making sure that the value setting for browser.backspace_action is equal to 2. But that didn't change the annoying behavior. Is there any other value I should try? It's not clear what the number means.

Nor did setting browser.backspace to true (or to false) seem to help with the unwanted jumping upon use of the backspace key.

This only seems to happen with Facebook, but it's quite annoying.

After firefox update to 100.0 - i can't use any of my addons, and cant install new one. All my current updates appears in "disabled" status, and there's no "enable" button. I have many addons, so it's the global problem.

Also, i can't install any of updates from addons.mozilla.org, i get message "Installation aborted because the add-on appears to be corrupt". All addon xpi files are downloaded without problem using "save as", also, after clicking "install" on addons website i see download progress.

Please help to resolve this issue!

After the latest Firefox update, some of my sites are returning "Network Protocol" Errors. I can log in on other browsers, but Firefox is the one I normally use.

Firefox crashes when switching between tabs. Worse than usual crash, the last page i was viewing is there but unresponsive to mouse or keyboard including contr-alt-delete. Must push and hold the power button on my Dell XPS8940. Windows 10 Home 21H2 OS Build 19044.1586. Windows Feature Experience Pack 120.2212.4170.0.

There was a window with 7 tabs, 1 playing a youtube video and 5 with videos not playing, one other site with no audio and another window with a website streaming only audio. When the system stopped, the speakers made an odd sort of buzz sound until powered off. I am on the latest version FF 99.0.1 but a similar crash happened on version 98.0.1. Before that this Dell never locked/crashed up this way.

This Dell PC has Realtek audio just like our HP W10 laptop and they both had issues when new with all sound not working when playing a youtube video only in Firefox (HP Feb 2021 and Dell Oct 2021). Launching Groove Music and playing an mp3 always got the sound working. Problem did not cause any program to crash. Windows updates to drives eventually fixed the problem but it only even happened in Firefox. Current problem is new in the last month or two and only on Dell.

Hi

For some reason i have to format my PC, so i took firefox profile backup "a4bbv2q5.default" and after reinstalling windows and firewall I copied the content of a4bbv2q5.default to new profile "n9pw9oja.default-release". But as i start firefox the important files get renamed "corrupted" and a new file replaces, hence my restore of old profile is not completed. Screenshoot for reference.

Please help and assist.

Firefox is not able to perform any download. It allways get a message saying that the download has failed. I´m completely out of solutions to solve this issue. Francisco

There are a number of old threads regarding this and having worked through them it is still unresolved. 1) I have cleared cache/cookies 2) I have disabled all extensions 3) I have turned off tracking 4) I have tried in safe mode - still the same.

This is not just on one website - it is on ALL that have Facebook feeds. It is NOT just on my laptop - I have asked others to try - they have the same result - blank page. ...so please don't suggest re-installing Firefox!!

An example is: https://dragonsdensoftplay.co.uk/News-Events/news-events.html

The feed works ok in other browsers.

Thank you

I opened Firefox as usually, but passwords are missing, only logins are available. There is also a file called logins.json-1.corrupt in the profile folder.

Renaming it back to logins.json with restarting the computer does not work.

There are no previous versions of these two files available in the system.

Please let me know how I can recover passwords, may be with a special software.

Thank you!

Hello. Since I use the bookmark bar and fullscreen mode a lot, I would like to be able to see the bookmark bar in fullscreen, not on every tab, but only in a new (empty) tab, so that I can avoid disabling fullscreen to access the bookmark bar and at the same time not having any part of the interface visible unless I'm in a new tab. Thanks in advance for any reply!

Until the last FF release (99), when I downloaded files from my bank for MSMoney FF would apply the action to use the MS Money import handler. Not anymore. FF will now only save the file. Even if I choose "always ask" it still just saves the file - never asks what to do with it (save or open with). Please fix this. It's worked fine for decades and now doesn't work at all. I tried adding images to show what happens but the ones that show what FF is doing and the FF settings won't upload. Only the banking download page images will upload. They just show that I pick MSMoney as the download format.
