I have a number of documents I want to embed in webpages for easy access. These are PDFs generated with pdftex locally under MikTeX. They use Adobe Minion Pro font. They render flawlessly in Adobe Reader, Sumatra, PDFXchange, and in Chrome (with its built-in viewer). They are also fine in APV PDF Viewer (MuPDF library) and PDF to GO (Documents to Go) on Android . . . you get the idea. But in Firefox they render interspersed with random characters. Example pdf and screen captures available (I don't see a way to post them).

In the meantime I've replaced the PDF.js with the Adobe Plug-in which fixes the issue for me. I'm concerned about others who may visit the site with Firefox as the default setting leaves these documents all but unreadable. Must I alter them to use a different font in order to preserve compatibility with pdf.js? Minion is widely distributed and well regarded (and not cheap) it would require significant adjustment to the formatting as well . . . Please advise.

I am almost positive that I have either a virus or malware or something like that but none of my anti virus or malware/spyware software is finding it. My browser began running very slow and now almost every single website that I go to has a bar at the top of the page that says, "Firefox prevented this page from automatically redirecting to another page". First of all, YAY! Thanks Firefox for saving my butt. The problem is that I have no idea what page I am trying to be directed to and I believe that knowing the URL could possible help me pinpoint the virus (etc.) that is infecting my computer or browser. Is there any way to find out what web page I am being redirected to without clicking "Allow" and possible further infecting my system? If not, it should definitely be an option to view the URL.

Suddenly, since the latest update (20.0.1) my right-click menu is terribly LONG. It's filled with things that seem useful, but are not to be and are not necessary at all. E.g. it contains video-control options, like mute and play, go full screen.

More weird and worse above this is: absolutely nothing in that same menu works or does anything. I

Here is a screen capture of it. It is the regular menu, randomly clicked, which appears everywhere. http://s23.postimg.org/ur0zwg4bf/regrigclibar.png

What's about this? Bug? I think anyway it is broken and needs to be solved.

I used to be able to right click on a page and among the options that would appear would be the possibility to save the 'visible portion' of the viewed page. It appears that this is no longer an option. How do I make this option available?

I am running Firefox 20.0.1 on Windows 7. The option is very convenient for keeping a record of paid bills, etc. when they paid company offers a confirmation or similar number for my records.

How to know if the page someone is browsing is HTML5?

For example, if I'm browsing php webpage then I right click on the page and "View Page Info", I get this: Type: "application/xhtml+xml".

I tried that on HTML5 webpage but I got the following: Type: "text/html".

My FF is automatically upgraded to v20.x.x few days back and it has been a constant struggle to use after that.

Issue : Whenever i'm trying to open any link in a new tab by doing right clicking into it or any other task which include right clicking on the page, the context-menu getting opened is of WHOLE PAGE LENGTH, even bigger then that. Problem doesn't end here but the main problem lies in the fact that NONE OF THE OPTION work from context-menu.

I've not installed nay plugin or add-on before or after the upgrade nor have changed the config settings so not able to understand the issue. looking for the option to attach a screenshot but unable to do that but let me know if anybody want to have a look into that.

cheers .. rahul

I recently got the Firefox 22.0 build 20130514181517 update (at the same time as a Windows 7 update, I might add) and since then the default font sizes on all websites have been enlarged. I have a 17" monitor, but due to the grossly overscaled fonts it seems more like an old 14", and it's quite irritating. To view the websites in approximately the old way they used to look, I have to zoom out twice, but it also means I have to do it on all sites. I also have the habit of accidentally zooming in or out while using my laptop's touchpad, so whenever I ctrl-0 to reset the font, it goes back to the large font, and I need to rezoom it again.

I am primarily trying to figure out if there is a way to reset the font size without using any add-ons.

Thanks

I've been using Firefox since well, lets just say long enough... Version 20 for the Mac seems to not have fixed any bugs or memory leaks.

One of the "fixes" is to restart Firefox, which is the only "fix" that works, but this really isn't a fix, this is a stopgap situation, in where you release the memory by closing it...

Are there other people with this same situation? My Firefox uses with nothing in the main page except google.com, if it's open for over 24 hours over 1GB of ram... 2 GB in 48 hours, etc...

The most Firefox has ever used was 5GB before I shut it down, now I know, restarting Firefox seems to stop this from happening, but as I said, this is a stopgap, there is something inside Firefox that makes this happen.

Is there anything in the future that will fix this issue, or is Firefox going to be forever a Memory Hog worse than Microsoft Office?

I tried to hear a conference call on a website. Got a message, needed windows media plug in. Checked my plug ins, no windows media. Read tutorial on firefox support. Clicked on download. Got a window that asked for repair or change. Tried repair, then change. Need better directions on how to finish download. Got message download successful, but after closing firefox and reopening, still no plug in for windows media in list of plug ins. Went to site and could not hear conference. Read support forum. Message about using about:config. Tried this, typed in about: config in start menu, but didn't see anything that looked like I could change to true like message said. solved by opening internet explorer and going to website and listening to conference call on windows media player. There was a message saying click here if you want to enable media player. Did so, heard conference. Tried using chrome. Got to hear conference yesterday. Today, there was same message about needing plug in when I tried to follow instructions to get plug in, it was as confusing and useless as firefox. The bottom line is I tried to do everything set forth in firefox's forum suggestions and can't get the windown media plug in to show up in my list of plug ins and can't hear conference calls on firefox. Chrome did say they were working on getting plug in available at chrome store. I agree with comments that I was able to go to web sites and hear calls before firefox made an update that removed my windows media plug in. The simple download fix, presumeably from windows, does not work, apparently because firefox can't find the fix. That is not the user's fault, and it looks like windows tried to provide a fix, and firefox won't recognize it. Bottom line, it is easier to use another browser, than try and get the windows media player plug in installed on firefox. What good is a browser, if you can't hear a call on the website that the browser takes you to? Please make it easy to install the windows media plug in on firefox. Thank you..

I'm using Firefox 20.0 on Fedora 17 (Xfce) fully updated. At random intervals Firefox will either set the language to some random version of English (Zambia, much of the time) until I notice and set it back or it will simply uncheck US English without selecting anything else. It also turns the spelling checker off once in a while. It's hard to say just what, if anything, triggers this because I only close Firefox for updates, and only reboot for kernel updates. Most of the time, my computer runs 24/7 and Firefox stays open sometimes, for over a month without any other issues. I found two old, closed threads on this, but neither of them had anything applicable.

When I start downloading multiple files using firefox DM, internet bandwidth is shared with active downloads without any browser activity.

Is there any way to set active download to 1 and queue all download which will start one by one automatically? This will help in downloading during low bandwidth connection.

Thanks, Jitender.

The printer was working fine. Suddenly that changed. Now when I print, the print is huge and a large part of the text is cut off. I tried reducing the size of the font but that did not help. This had happened to me before about a year ago and I tried different things with firefox and was finally able to fix it. However, this time I have tried all your troubleshooting tips and nothing works. The print function was working normally up to a couple of days ago and to the best of our knowledge neither my husband and I have made any changes to the settings.

hello when using 22b1, I find out that my lingoes text capture plug-in doesn't work properly. It only works with translate selected words, but the function capture word on screen doesn't (right click + function key on word to translate). so now I have to move back to 21 hope you will consider this situation
