Adobe Flash 16 and 17 cause safari & Firefox browsers to jump up and down the page

Running MAC Pro 2010 10.10.2 Yosemite - Version 15 of adobe Flash was working fine. When version 16 came out the problems started with web pages jumping up and down and not being able to type/ edit things as web page jumps up or down away??? I Used the adobe Uninstaller , restarted the MAC, looked for the files in the library adobe said to look for ( non were there) and tried to install Adobe ver 15 of flash
And it starts to install, then the install window turns BLACK then the error message says install failed?? Try again? I have tried this a few times and always the same message.
Any idea how to install this older version 15??

It's not really the politics -- we're all pretty friendly on an engineering level (the business stuff is competitive, but that's always the case), but in how serious the security landscape is. There are armies of people reverse-engineering and weaponizing bugs in all popular products (often times way more people than work on the products themselves), and the time it takes to reverse-engineer the patches in a current version to weaponize and use against older versions is really short now. If you're not staying updated, you're a sitting duck.
If you look at this from an immunology perspective, what we don't want is an epidemic, so just like we do with childhood diseases, we want to maintain herd immunity. If 95% of the population is patched, it's difficult to deploy malware that spreads like wildfire. If you have a population that never updates (it used to take about 6 months for the majority Flash users to pick up the latest version, now it's closer to 48 hours with background update), even attacks that you've already fixed remain viable for months. If attacks have a short shelf-life, this pushes up the cost of developing the attack to where it's out of reach for most bad actors.
The Extended Support Release I linked to above *is* an older version of Flash, but it has all the latest security updates. It also won't be blocked by Safari. If the problem goes away, it's something that we broke in a new feature. If it doesn't, it's fallout from a security change, and I'd like to get more info on how to reproduce it, so we can try and fix it for the next patch update.

How to disable a flash trace in safar & opera browsers.

hi
I have installed flash player (16) debugger version for Mozilla, Now I am getting flash trace in mozilla, safari & opera. I want to disable the flash trace in safari & opera.
Please tell me how to do this.
thanks in advance

Yeah, the debugger is for developers that need to write and debug Flash content. You don't want to use it for general browsing. It's much slower than the release player because of all the tracing, and it shows you everyone else's coding mistakes that didn't get fixed before they shipped (and there are a lot).
So, you'll need to uninstall and move back to a release player. What most of us do is keep the debugger in one browser (like NPAPI Flash Player for Safari/Firefox) for doing web development, and then use another browser with the release player for actually browsing the web (like Chrome). Since we're using two browsers with different plug-in architectures, we can keep them installed in parallel instead of switching back and forth.
Anyway, here's the uninstaller:

Then just download the regular installer at:

Unable to install Adobe Flash Player in Mozilla FireFox

I am attempting to download and install the current Adobe Flash Player using Mozilla FireFox 19.
When I go to the download page this is what I see - no Download Button:
http://awesomescreenshot.com/02411pbs45
I have disabled my AV - no change. I have the latest version of Java activated.
I do have Adobe Flash Player 11 ActiveX installed in IE 10.
I run Windows 7, 64 bit, on an HP Pavilion dv7.
Thanks.

Could not see how to reply on the discussions page so am replying here. DOH! Was not signed in.
I only use FireFox and rarely IE.
Went to the provided page and saw this:

In the meantime I was able to download and install Adobe Flash Player 10. Will work with this in the meantime.
Thanks.

How to watch flash based videos without adobe flash installed using Safari

How do I watch flash based videos without adobe flash installed using Safari?

Once you have Chrome installed, activate the Develop menu in Safari (go to Safari Preferences > Advanced > Show Develop Menu). You then will see under the Develop menu the Open Page With option and Chrome will be listed there.
So each time you open a page with Safari requiring Flash, you use that menu option to open the same page in Chrome.

Hi, glad that worked for you. Also thanks for the explanation as how you came about this. Yes, from my understanding any Install of the CS5, even a trial version Installs the 10.1 (beta/prerelease) versions. It is not clear to me or others why the 10.1 was used in the CS5 instead of the latest version (10.0.45.2). My only guess is that the 10.1 is very close to being released as a shipping version (final release) to the public. The 10.1 had a target date of the first half of 2010. Perhaps that was the reasoning. This is just my opinion:-)
As I said, many users are having this problem, not just with the CS5, but they Install the 10.1 thinking that will solve whatever problem they may be having with the latest version.
Your thread is very helpful for other users that may be having the exact problem that you were. For this reason if you marked your thread as answered, they would read it first.
Thanks,

Adobe Flash not recognized in Firefox 5

I have uninstalled and reinstalled the current 10.3 version of Adobe Flash player. It registers fine in Chrome and Safari, Firefox 5 does not see it. The Flash plugin is in the proper path for Mac users (Library/Internet Plug-Ins/) along with all the other usuals Flip4Mac, Java, Quicktime etc... I don't know what else to do.

I have this problem with FF5 on both Win7 and Snow Leopard.

I have Adobe Flash Player Plugin for Firefox, but I'm still missing Flash Player?

So I have installed the latest version of Adobe Flash Player Plugin for Firefox, and I'm able to watch youtube videos on my browser and other things that require flash player, but I have a disc that i got along with my Samsung monitor, and when I put it in my computer, it says that I do not infact have flash player. Also, when I try playing a game, DawnGate, theres a black box where a video should be, and it says that i do not have flash player, and it is required to watch these videos. I tried uninstalling, and I was unable to watch youtube, and when i reinstalled, I was able to watch youtube again, but that did not fix my problem. Is there something I'm missing? I look forward to hearing from someone soon.

Odds are it's looking for the IE plugin: (A lot of software just assumes ALL Windows users are "slaves to Microsoft" and only have IE installed.)
Flash Player for ActiveX (Internet Explorer)
or the standalone Player:

Adobe Flash Player crashes on Firefox (NetSteam, Stratus)

Flash Player version: 11,8,800,97 (last)
OS: Windows 7
Browser: Mozilla Firefox 22.0 (last)
Problem: Adobe Flash Player crashes on Firefox, when runnig project with such elements like NetSteam, Stratus.
When problem happen: Only when some streamed data is incoming, after random time. Time before crash can be 4 minutes, it also can be 2 minutes. Memory leaks or disk space usage didn't change and don't seem to be a reason. Problem happen when I was testing my voice chat together with few people. At one moment it crashed at few computers at the same time (which were using Firefox). Then we had luck with repeating this problem several times - simply by asking one of us to play any music into Microphone. Then Firefox Flash Player always crashing.
Here you can see repeating of problem: http://youtu.be/BdkoQxloyDA
It also show that it does not crashes if nobody is sending audio stream in created group, but it does when somebody is sending audio stream. In that video I'm repeating problem by myself, with help of one computer and 2 tabs of Flash Player. First is running in Chrome, second in Firefox. Player in Chrome is used to send system sound from speakers to peer group. Player in Firefox is listening and playing everything he hears (this is why I set it's volume to near 1).
Here is .swf :

It's very simplified voice chat which only displays streams which are being heared. It's adding " is talking" when stream is sending data. "g" parameter is a group name, I think you can choose any, but tests were made with this one.
Hope it helps. If you will need .fla file - just tell me.

Your issue is distinct from the original poster's issue about a crash on Mac. I've branched this out to a new thread so that we're not confusing everyone.
Firefox on Win8 isn't very stable. We're collaborating with Mozilla on improvements, and my test results with the daily development builds are really promising, but it will be a few more weeks before they actually make it to production releases.
In the meantime, you're way better off using IE or Chrome.

Problems installing or running Adobe Flash Player for safari

problems installing or running Adobe® Flash® Player for safari when trying to install Adobe Flash Player.pkg it asks to quit Dash Board client then brings up Exclamation mark up and quits install ??????

Adobe Flash is pretty much a 32-bit application. You may be able to fix the problem by going into your Applications folder, and right-clicking on Safari. There is a check box that will allow you to run Safari in 32-bit mode. Try that and see if Flash works in Safari.
I have retired my iMac, and have an HP now, but a friend helped me with the same problem when I upgraded to Snow Leopard. My PC seems to have just one 64-bit browser, that being Internet Explorer. I am using IE9 Beta in 64-bit, and the Beta for Flash "Square" in 64-bit seems to work fine. See link below:

How to intercept the Adobe Flash plugin block by firefox checking for vulnerabilities?

The trouble is the grey block, that asking to update Adobe Flash because the version is vulnerability. If the block of Flash object is smaller, then 100px height - there is an empty space, but not gray block with talking about version. I need to intercept the moment using JavaScript, when Firefox checking the version of plugin to make changes in my HTML code to make a GIF, but not flash.
How to intercept the Adobe Flash plugin block by Firefox checking for vulnerabilities from JavaScript code?

hello, i don't think that this would be possible (but i'm not sure). what you could do is try to sniff the version of flash that is installed & the firefox useragent and just assume that old versions of the plugin will be blocked in this combination.
if you need more help about that, i'd recommend posting in a forum that is more specialized & knowledgeable in web development like http://forums.mozillazine.org/viewforum.php?f=25, since we here on the firefox support forums are primarily focused on support for end-users...

Problem updating Adobe Flash Player with Safari

Hello!
I'm trying to update Adobe Flash Player using Safari on a Macbook Pro with OS X 10.10.1 but every time I download the update the file looks like this:
and when I try to start the installation this window appears:
I tried several different download links but non of them worked. I also uninstalled the Adobe Flash Player and tried to reinstall it but then I have the same problem. Any ideas on what I'm doing wrong? Thank you!

For some reason that I have yet to determine, people with Matlab installed start getting .mdlp extensions appended to their downloaded files. That's what happened here. Rename the file to remove .mdlp (so that it ends in .dmg), then double-click the file and it should work.

Adobe Flash will not update to a W-2000 system and will not work? Is there a fix? Mozilla has disabled Flash. Do I have to go back to Explore?

Having trouble watching live streams such as jtv and twitch.tv. I tried uninstalling/reinstalling adobe flash but I still get no stream just ads and pictures. Anyone have any suggestions?

I just wanted to follow this up by saying that you were entirely correct in your diagnosis of the situation. My computer did have the faulty part you linked to. I brought my laptop in and specifically told them to run that test, had it fail and then argued with the person at the genius bar and the manager. Eventually they offered to have it sent out and have everything replaced for free of charge. They did so mainly because I had complained about graphical issues almost every other time I had come in with problems and no one ran the test. They should have caught this problem during my warranty, but they didn't, even though I mentioned the problem.
Anyhow, after having the part replaced, I haven't had my computer crash a single time since, or had many of the issues mentioned above. I've never had this experience before. Even brand new, I got occasional crashes. Hopefully this new trend continues.
I do find that web browsing is still incredibly slow. Web browsers just chug along at a slow pace, even though I have great internet speed. Maybe I'll try just deleting my web browsers and reinstalling them...
Anyhow, thank you for your help and knowledge Clinton.
