Why so many ports opened?
This is my last straw using Firefox unless this is remedied. . Open any webpage with Firefox and literally HUNDREDS of ports are connected out. One time I counted 278 ports were open (screen capture then counted). This slows my PC down to a crawl to the point of freezing up. Nothing in the browser will work until, usually about a minute later, ports start to close. I do not want to hear it is my PC, this problem did not happen in 10 or so previous versions of Firefox. This port opening problem was slowly growing over the last (about) 10 versions. EVERYTHING on my PC is up to sate, drivers, hardware, etc. and yada-yada. IT IS NOT my PC, it is Firefox software.

ALSO: __ The last 2 FF versions. __ I watch many news videos, FF will not play said videos due to "message in video" browser incapability. __ Firefox browser is supposed to be the best browser? NOT if this happens. AND YES, all software is up to date, so DON'T bother saying that.
A lot of websites will use an HTML5 media player to play media files. You are on Windows XP and unfortunately there is no native support to play MP4 files on XP. That would explain error messages about not being able to play MP4 files.
For the YouTube website you can use an extension to get the Flash player instead of the HTML5 media player.
Also make sure that WebM is enabled.
These prefs should be set to true on the about:config page:
- media.mediasource.webm.enabled
- media.webm.enabled
You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.
What if you open a page that only connects to a single server such as this HTML5 audio format test page: http://hpr.dogphilosophy.net/test/ (sends two requests to one server, total)
Do you still get a bunch of ports opening?
If so, could you test in Firefox's Safe Mode? In Safe Mode, Firefox temporarily deactivates extensions, hardware acceleration, and some other advanced features to help you assess whether these are causing the problem.
If Firefox is not running: Hold down the Shift key when starting Firefox.
If Firefox is running: You can restart Firefox in Safe Mode using either:
- "3-bar" menu button > "?" button > Restart with Add-ons Disabled
- Help menu > Restart with Add-ons Disabled
and OK the restart.
Both scenarios: A small dialog should appear. Click "Start in Safe Mode" (not Refresh).
Any improvement? (More info: Diagnose Firefox issues using Troubleshoot Mode)
I know about and done the Safe Mode in the past, didn't work. What partly did work was... "These prefs should be set to true on the about:config page:
media.mediasource.webm.enabled media.webm.enabled "
I say partly, a webpage opening is a little faster but now after clicking on a page to open it does not do anything for about 3-5 seconds. It seems to be buffering before loading or storing to memory then POOF, open. But overall it is just a little faster. . As for the videos. On this PC, back in original HTML days, videos loaded fast and ran smoothly. Also, skipping ahead or back instantly worked. I can only 'assume'... HTML5 is the problem. It is doing more than it used to and HTML (now #5) is becoming incompatible to my PC and sure millions of others. Personally I have closed the webpage long before it has loaded. It is there loss if said info goes unread or selling item isn't sold. . BUT HEY! Thanks for the direction to update the about:config thing. It REALLY should be loaded in the OPTIONS menu. AGAIN, THANKS!
Firefox currently does not have a feature to block loading of video. There is a feature to stop video from autoplaying, but it still loads. If you want the option to watch videos in WebM format (which you disabled) without the drag of loading the file at the same time as the rest of the page, you would need to find an add-on that intercepts the load before it can happen. I don't recall seeing one, but perhaps someone has created one by now.

Forgot to add... Mozilla really should offer Firefox in "Classic Mode" for older PC's. There are BILLIONS of single core CPU's still in use.
Blocking of video loading, ZAP still works well for that.
(posting here between jobs) The Add-on "YouTube Flash Video Player" did work. THANKS!!!
Another oddball thing. Webpage loading now (HTML5) seems to be Loading-stop-load another thing-stop-load another thing-stop-load another thing-stop... etc. until complete. Is this a jscript problem? As I look at 'Page Source' I'm seeing A LOT of jscripts.
Hi fm.usa, what page are you talking about? Popular sites tend to use a lot of resources. Firefox only opens a certain number of simultaneous connections per site. Have you used the Network Monitor to watch what's coming in and where bottlenecks might be?

It's any page that has a LOT of stuff to load. I look at (right-click) 'View Page Source' and see thousands of code lines. Many of that code is jscript. I thought JAVA was unsafe?
(I shouldn't be posting while doing other jobs, sorry for these multi-postings) I'm assuming the bottleneck is my old (2005 Dell) single core CPU PC. It's maxed out, Intel-3.0 CPU - 3.5GB memory - 512 Mb graphics card, 48MBPS IP connection. What is VERY strange, brand new 1.8 CPU Laptops and Desktops are faster than my 3.0 CPU? I also have a 2003 Laptop Dual Core 3.2 CPU - 3GB memory - 256 Graphics card and pages load slightly faster. probably due to Dual-Core.

The Network Monitor is not a raw source code view. Check it out. Press Ctrl+Shift+k to open the Web Console in the lower part of a tab, then along its top bar, click Network. Reload the page in the top part of the tab and watch the wide range of resources the page is calling come in.
JavaScript is pervasive on the web, while Java is a plugin used for applets or games on a small number of sites. Some code is safe, and some isn't. Plugins have privileges that extend further into your system than web page code, so those tend to raise more concerns.
It does take a lot of horsepower to compute modern page layouts...

I figured that. That's where Mozilla should offer a "Classic Browser" for the older PC's. . OK, I'm done with this thread. I got all the info needed and thank you for that. Have a good one.
Mozilla does offer a "Classic Browser" for older PC's. It's called ESR, the Extended Support Release.
The current version is 38.6.1 and is the browser I use daily on XP with Pentium M and 2GB RAM. It's plenty fast. Maybe your hard drive is a bottleneck if it's only 5400RPM; I have a 7200RPM.

I'll try that CB-ESR 38.6.1 I did upgrade from IDE 5400 to Sata 7200. Some improvement but went more for storage, yes it gets Defragged every week. . Like I mentioned, I didn't have this problem 2.5 years ago and nothing changed in my PC. Only other thing is, web-sights using the new page code. Somehow I don't think the Classic Browser will make much difference, but will try.
The Extended Support Release is not hugely different from Firefox 44, since it is based on last year's Firefox 38.
I prefer ESR because it includes the necessities without all the bells and whistles of the conventional Firefox.
That being said, I still recommend the standard version of Firefox for regular users. It's all about what works for you and makes you happy!
