Firefox 技術支援討論區

Last week Adobe Flash stopped actuating/working with Firefox and there is no black box in the address bar or any place else that I see that asks me to activate it. I have it set as Always Activate on the Plug-Ins page but that isn't helping. I checked and have the most recent version. I had to go through several steps to activate it but it does work in Chrome. I run Win 7 and Firefox is my default browser. Please advise how I can get Flash to work again as it is hampering a lot of my activity on the web. Thank you.

...Pretty much exactly like the title says. I checked the plugin checker after updating to Firefox 30 to see if there was anything that needed updating. Of course, there was: Shockwave and "Adobe Acrobat NPAPI Plug-in".

While I was able to get Shockwave up to date just fine, the Adobe Acrobat NPAPI Plug-in is presenting some trouble. As in, when I click "Update Now", instead of redirecting to an update page, it redirects right back to the Plugin Check page.

Where can I go to update this plugin? Does it need to be updated? Is this a glitch in the checker, and therefore I don't need to do anything?

I'm using Firefox ESR 52.9 because it is the latest version that the Pocket extension still works with. It just suddenly (without any updates or warning) disabled the AdBlock Plus, Roboform, and Google Shortcuts extensions (all of which were working perfectly fine yesterday) because "they cannot be verified." and it isn't giving me the option to re-enable them.

The info at https://support.mozilla.org/en-US/kb/add-ons-disabled-or-fail-to-install-firefox?redirectlocale=en-US&redirectslug=add-ons-failing-install-firefox and https://blog.mozilla.org/addons/2019/05/04/update-regarding-add-ons-in-firefox/ is not helpful because the verison of Firefox I have doesn't show the studies option that is referenced there.

And an update that is to Firefox ESR 53 or later also isn't useful because then my old Pocket extension won't work (and that extension is KEY for me). Please provide an immediate fix for Firefox ESR 52.9.

The Firefox plugin checker is reporting "vulnerable - Update Now" for my Java Deployment Toolkit 7.0.510.13. and Java(TM) Platform SE 7 U51 plugins.

The 'update now' link takes me to the Java download page which invites me to download the latest Plugin 7.51. but i already have 7.51 installed so the plugin checker is incorrectly displaying "vulnerable - Update Now". I have had 7.51 installed since January 17th and run the plugin checker on a weekly basis so i'm not sure why it has suddenly decided that this is a vulnerable plugin.

I am running Firefox 28.0 on Windows 7

thanks ...

I go to a website that requires a Java plug-in. I downloaded the latest update (21) for Java 7 from Oracle but when I go to Add-Ons>Plugins in Firefox 20 the Java plug-in doesn't appear and when I do a search at the Get Add-ons nothing that mentions the Java Plug-in shows up. Where can I get the plug-in required to use with JRE7u21?

Mac OS 10.7.5, Firefox 20.0, Java Runtime Environment 7 update 21

What is this mess? FF automatically upgrades to new version without permission and takes away my session manager, meaning my last session. I don't know why restore previous session is highlighted but won't do anything when clicked. Im using windows 7.

Until today the options for stopping videos auto playing worked OK, suddenly they don't work at all. I had changed all the settings in about:config - please see screen shot attached - a couple of weeks ago when they suddenly started auto playing and that solved the issue, but now I am back to square one. Even when I have ensured that the autoplay option is changed in the preferences section they are still auto-playing. Any suggestions please as this is driving me crazy!

Thanks in advance for your help. It is much appreciated.

I already have ABP Adblocker installed, but this one tab keeps popping open for some reason. The name of the tab reads Sponsorship, and the url it sends is:

I'm getting pretty sick of it because I thought I was going to get away from pop-ups on firefox...

I've used Theme Font & Size Changer for years to enlarge Firefox's font. I was just updated to Firefox 57, & the font (on toolbars, tabs,etc) is so tiny. TF&SC no longer works in 57. Is there another way to enlarge so I don't have to squint? (To be clear, I'm not asking how to increase font on a webpage)

After installing v65, when I go to the addons menu, no items are showing. Evidence exist they are there 1/ I have addons working quite well with this version, I tried a new theme which after a few re-starts, eventually took hold 2/ when I do open add ons menu, there is evidence that there is a list there, but they are only place holders. My mouse shows a blue line around the entire field, but absolutely nothing inside... like a white out. So I can't uninstall themes, even though I have installed a trial one... nothing at all appears. HELP!

Why does it seem like every time Firefox installs an update, all of my add-ons disappear?!! It is so GD infuriating and frustrating, because I have to go back and figure out which ones I had and reinstall them... Why is that even a thing? Why would they design their stupid browser like that? Please correct me if I am wrong and tell me what I am doing wrong....

Why the download style at firefox 26 are changed?

Some questions:

01. How i can return to old style of downloads?

02. How i can make all the files it downloaded AUTOMATICALLY and instead cleared from download list window? http://postimg.org/image/4tmf23tnj

03. Why every file i download from firefox 26 it has the lock icon? http://s27.postimg.org/ozpx0zpb3/image.png

Both of them DOESN'T happening at firefox 25 and older version.

I delete Default Browser and all other search engines except Google. I then get Google search results for a bit but then later on I start getting a Yahoo panel at top of browser page. Go into Preferences and it shows under Search Engines a Browser Default. Can't get Firefox to stop going back to Browser Default which seems to be Yahoo. Any help appreciated. Thank you

I'm running Adobe Acrobat 8. I'm happy with it. Firefox has a new feature that automatically disables the PDF plugin unless it's clicked. It's called the "Click to Play" feature. Even when disabled, it's not really disabled: it activates itself for "vulnerable plugins." Though there is an option to make a website trusted for plugins, there is seemingly no way to make the PLUGIN ITSELF trusted. As a result, every time I get a PDF, I have to Click to Play.

Question: How do I truly disable this stupid new feature?

There is the following support article that explains this new system, and that the only solution is trust a website, but apparently can't disable the feature or trust the plugin:

I got hit with the fbi scam virus (don't know how as I use a Mac) and I don't know if its gone or not but I reset FF to its default state using the procedure outlined here. https://support.mozilla.org/en-US/kb/reset-preferences-fix-problems

But after doing this, all my settings, my user profile and my exceptions list in privacy that I have been painstakingly putting together over years, has just disappeared and I am quite annoyed.

If these settings are recoverable, how do I restore my previous FF state?

In Options, I have C:\Downloads⁩ as the location that my internet files are downloaded. Instead, they go to a different location, specifically: C:/Users/**/AppData/Local/Temp.

How do I make Firefox download my files to the correct location?

Thanks.

I am a computer dummy. Firefox is installed in our Windows 8 computer as our browser. Whenever we use it, a very annoying thing called Default Fire Fox Developer tools comes up at the bottom and takes up half our screen. Sometime it lets me hit esc. to close it but then it just pops back up. We use our computer for the net, e mail and social media alongside learning sites for our kids. How can I get rid of this thing? Please help me and explain it like I am 6 .
